One day in the spring of 2009, Edward Tufte, the statistician and graphic design theorist, took the train from his home in Cheshire, Connecticut, to Washington, D.C., for a meeting with a few members of the Obama administration. A few weeks earlier, he had received a phone call from Earl Devaney, a former inspector general in the Department of the Interior, who is best known for leading that agencys investigation of the lobbyist Jack Abramoff. Devaney had recently been appointed head of the Recovery Act Accountability and Transparency Board, the body created by the Obama administration to keep track of the $780 billion in federal stimulus money that has spread out across the country.
Whereas Devaney once led a team of professional investigators responsible for sniffing out waste, fraud, and abuse, he was now faced with a rather different, but related, task: designing a Web site. In the stimulus bill, Congress had called for the creation of user-friendly visual presentations of data that would allow the American public to watch over the disbursement of the giant funding package. This wasnt exactly familiar territory for Devaney, a career lawman. Perhaps Tufte could offer some advice?
And so, that April, in an office building blocks from the White House, Tufte spent a few hours with Devaney looking at sketches of some of the displays the board was preparing. Devaney showed Tufte a prototype of Recovery.gov, the site that catalogs all the projects funded with federal stimulus money around the country. Thinking about it now, Devaney remembers that the proposed pages were full of classic Web site gobbledygook, with lots of simple pie charts and bar graphs. Tufte took one look at the Web site mockups that the boards designer had prepared and pronounced them intellectually impoverished.
It was a classic Tufte moment: a spontaneous and undiplomatic assessment that immediately struck everyone in the room, even the designer himself, as undeniably true. The site would get a wholesale redesign. The model, as Tufte explained it, should be the Web site of a major newspaper, with Devaney and his staff as reporters and editors. I told them that it isnt an annual report, Tufte told me later. It shouldnt look stylish or slick. Its about facts. As Tufte and Devaney talked, a number of staffers gathered in the hall, waiting for the meeting to finish. The guys from the IT department had lined up outside my door to shake his hand and say they met the guy, Devaney remembers.
Edward Tufte occupies a revered and solitary place in the world of graphic design. Over the last three decades, he has become a kind of oracle in the growing field of data visualizationthe practice of taking the sprawling, messy universe of information that makes up the quantitative backbone of everyday life and turning it into an understandable story. His four books on the subject have sold almost two million copies, and in his crusade against euphemism and gloss, he casts a shadow over the world of graphs and charts similar to the specter of George Orwell over essay and argument.
Tufte is a philosopher king who reigns over his field largely because he invented it. For years, graphic designers were regarded as decorators, whose primary job was to dress up facts with pretty pictures. Tufte introduced a reverence for math and science to the discipline and, in turn, codified the rules that would create a new one, which has come to be called, alternatively, information design or analytical design. His is often the authoritative word on what makes a good chart or graph, and over the years his influence has changed the way places like the Wall Street Journal and NASA display data.
In policy circles, he has exerted a quiet but profound influence on those seeking to harness the terabytes of data flowing out of government offices. In recent years, several large American cities, including New York, Oakland, and Washington, D.C., have opened up entire universes of municipal statistics, giving birth to a cottage industry of programs and applications that chart everything from the best commuting routes to block-by-block crime patterns. And under the Obama administrations Open Government Directive of 2009, the federal government has been releasing scores of downloadable data sets. In the public realm, data has never been more ubiquitousor more valuable to those who know how to use it. If you display information the right way, anybody can be an analyst, Tufte once told me. Anybody can be an investigator.
Tufte is equal parts historian, critic, and traveling revival preacher. For a few days each month, he goes on the road to teach a course called Presenting Data and Information in hotel ballrooms and convention centers. One afternoon, shortly after his meeting with Devaney, Tufte was teaching his course in the downstairs ballroom at the Marriott hotel in Seattle, Washington. There were 400 people in the crowd. Tufte, who is sixty-nine, and has a thinning slash of silver hair and a pair of wire-rimmed glasses that hang off his nose, was standing at the front of the room. He was wearing a wireless microphone, and held a copy of a small map above his head.
This, he said, is War and Peace as told by a visual Tolstoy. The map is about the size of a car window, and follows the French invasion of Russia in 1812. It was drawn in 1869 by a French engineer named Charles Joseph Minard. On the left of the map, on the banks of the Niemen River, near Kovno in modern-day Lithuania, a horizontal tan stripe represents the initial invasion force of 420,000 French soldiers. As they march east, toward Moscowto the right, on the mapthey begin to die, and the stripe narrows.
The map itself is elegant and restrained, but it tells the story of a sprawling, bloody horror: cold and hunger begin to finish off whatever French soldiers the Russians havent killed in battle. As the French army retreats, the tan line turns black and doubles back on itself to the left, or to the west, away from Moscow. A series of thin gray lines intersect the path of the army, showing the winters cruel temperatures. On November 9 it is 9 degrees below freezing. On November 14, it is 21 degrees below.
Then, on the 28th of November, a catastrophe: in a rush to cross the Berezina River, half of the retreating army, 22,000 men, drowns in the rivers icy waters. The black line, already thinned to a fraction of its initial size, abruptly reduces by half. Finally, in late December, six months after they set off, the surviving French soldiers cross back over the Niemen River. The map shows their number: 10,000 men. Ultimately, only one in forty-two soldiers survives the doomed campaign.
Tufte pointed to the far left of the map, where the tan and black lines intersect. And it is there, he said, at the beginning and at the end of the campaign, where we have a small but poignant example of the first grand principle of analytical design: above all else, always show comparisons.
Over the years, in his books and courses, Tufte has called the Minard map perhaps the best statistical graphic ever made, and his endorsement has turned this obscure historical artifact into something of a cult object. Tuftes long and discursive speech on the map serves as the dramatic climax of his courses, the equivalent of an old rock band playing its greatest hit on tour.
He usually does his explication of the map just before lunch. In Seattle, we were about to break, and he was finishing up. His voice quickened. Minard made this because he hated war, he said. The map wasnt about Napoleon, the wars surviving hero, who is mentioned nowhere on the page, Tufte explained, but of the quiet, anonymous misery of tens of thousands of French soldiers. This was meant as an antiwar poster.
The man sitting behind me, a middle-aged software engineer with a laptop, let out a puff of air. Wow.
The course finished at five that evening. I walked outside to the hotels parking lot, where a white stretch limousine was parked near the entrance. Two men in loose black suits were leaning against the hood, and they introduced themselves as the limos drivers, Vlad and Vlad. A minute later, Tufte came out, his face tired and hair wet. These shows can really wipe me out, he said. Behind him walked two roadies who travel with him from city to city, helping to set up the equipment for each class and handling registration. We all got in the limo, pulled onto Interstate 5, and headed toward Portland, where Tufte would be teaching the course again two days later.
Tufte, who taught political science and statistics at Yale from 1977 to 1999, first gave his six-hour course in 1993. Since then, more than 190,000 people have attended. The day costs $380, which includes Tuftes four books, which he self-publishes under the name Graphics Press. He is a very wealthy man. In his carriage and attitude, Tufte appears most comfortable still thinking of himself as an academic: at his courses, many people in the audience call him Professor, and during breaks and lunch he answers questions and signs books as part of office hours. (More than a decade after leaving the university, he still uses his yale.edu email address.) But he is not beholden to any institution, nor to any product except his own, of which he has become a highly refined salesman.
Tuftes rise mirrors that of information itself, which, since the dawn of the computer age, has infiltrated every aspect of modern life. If the production of data and its graphic representation was once a specialized trade, it is now accessible to nearly everyone. Information is all around us, but so is what Richard Saul Wurman, an architect who, along with Tufte, shaped the field of information design in the 1970s and 80s, calls non-information, the flotsam and noise that are the by-products of a hyperactively quantitative culture.
The modern history of information design has its roots in the Bauhaus, an arts institute founded in 1919 in Weimar, Germany. Later, in postwar America, designers like Nigel Holmes at Time magazine and George Rorick, who invented the modern weather map at USA Today, began to draw playful graphics that boiled down a question to a few numbers and then presented them in a colorful package. They were inviting and simple drawings, like a cascading stack of oil drums to show the rising price of oil, and were generally more full of good cheer than hard data. Tufte has derided the genre, calling them chartoons.
For a long time, there was a split between designers who were making graphics for mass consumption and scientists who relied on graphics to communicate their findings. What was meant to be accessible should not look too technical, while for those making complex and substantive points, there was a sort of honor in making impenetrable graphics. Making something look good was considered treacherous, said Erik Spiekermann, a German typographer and designer who created the typeface used on German railways. If you make something look pretty it means youre lying. If you want something true its got to hurt.
In his books, the first of which, The Visual Display of Quantitative Information, came out in 1983, Tufte aimed to destroy this myth, largely by relying on historical examples like the Minard map. Tufte killed the idea that we are afraid of numbers, said Tobias Frere-Jones, a typographer who keeps Tuftes books on a shelf above his desk in downtown New York. And once you get over that idea, you cant really justify the birthday-party-clown school of data visualization, where you need bright colors and shiny things to convey that the stock market went down this week.
Tufte has coined several terms that have come to define his style, such as data-ink ratio, the proportion of graphical detail that does not represent statistical information, and chartjunk, ornamental and often saccharine design flourishes that impede understanding. Jonathan Corum, a former graduate student of Tuftes at Yale who is now the science graphics editor at the New York Times, said that using Tuftes principles is a way of respecting the readers intelligence. I think of it like Im starting with this rough, unpolished stone, he said. So how do you cut the perfect gem?
Many of Tuftes neologisms have come to carry a sort of Talmudic authority in design firms and newsrooms, though they are also quoted by engineers, financial analysts, consultants, and, perhaps unsurprisingly, political strategists. Karl Rove, senior adviser to former President George W. Bush, attended one of Tuftes courses in Austin in the 1990s and considers himself a huge fan. I must have bought a hundredplus copies of The Visual Display of Quantitative Information for colleagues and friends, he told me. Particularly in the early days in the White House, someone would come in and show me a presentation full of chartjunkin this context, Rove explained, extraneous graphics or, say, bar charts drawn from interlocking dollar signsand I would send them off with Tuftes book to do it again.
Tufte may be one of the few theoristsdesign or otherwiselauded in both the Bush and Obama administrations. After their first meeting on Pennsylvania Avenue, Earl Devaney sent Tuftes resume to the White House, leading to his appointment last March as an official adviser to the Recovery Transparency and Accountability Board. But his influence in the administration has reverberated beyond that office. Peter Orszag, who left his post as head of Obamas Office of Management and Budget last year and then took a job as vice chairman of global banking at Citigroup, spoke to me recently in his office on the thirty-ninth floor of the banks headquarters in lower Manhattan. He was first given a copy of Tuftes Visual Display of Quantitative Information as a college graduation present. As Orszag explained, the challenge of designing graphics to represent the nearly infinite stream of data coming out of government offices is to be compelling but not to oversimplify. The description sounded like many of the maxims I heard on tour with Tufte. Indeed, at the end of our conversation, Orszag told me that Tuftes spirit has been taken to heart by an entire generation of data analysts.
Before his work with Devaney, Tuftes most public engagement with the federal government came in the form of a scathing crusade against its endemic use of Microsoft PowerPoint. In January 2003, the space shuttle Columbia took off from Kennedy Space Center. Seconds into its flight, a piece of foam insulation broke off from the shuttles fuel tank and punctured its left wing. For days, as the shuttle orbited the earth, engineers at NASA and Boeing debated how serious the hole might be. Much of this communication was done in the form of PowerPoint, a software program that Tufte says is constricting and obfuscating and turns information into a sales pitch.
After reviewing several PowerPoint presentations, NASA officials decided to proceed with the shuttles return flight. On February 1, Columbia burned up as it reentered the earths atmosphere, killing all seven crewmembers on board. Tufte has called PowerPoint a coconspirator in the shuttle disaster.
Tufte dissected NASAs PowerPoint slides on his Web site, showing that the program didnt allow engineers to write in scientific notation and replaced complex quantitative measurement with imprecise words like significant. He then published a twenty-eight-page essay called The Cognitive Style of PowerPoint, in which he analyzed hundreds of existing PowerPoint slides and showed that the statistical graphics used in PowerPoint presentations show an average of twelve numbers each, which, in Tuftes analysis, ranks it below every major world publication except for Pravda. The low information density of PowerPoint is approaching dementia, he wrote.
Later that year, in August 2003, the Columbia Accident Investigation Board issued its own report on the shuttle accident. On page 191, in a section called Engineering By Viewgraphs, the board cited Tuftes research, and wrote that it views the endemic use of PowerPoint slides as an illustration of the problematic methods of technical communication at NASA.
While PowerPoint still takes a rather severe lashing at Tuftes courses, he says he has largely moved on from the debate. Its a public and corporate disaster for Microsoft, he said. But its a trivial issue to me. The general backlash against PowerPoint has only grown, however. In 2009, Thomas X. Hammes, a retired Marine Corps colonel who is now a fellow at the National Defense University, wrote a widely circulated essay in Armed Forces Journal that argues that PowerPoint has had a toxic effect on the culture of debate and discussion within the U.S. military, claiming that senior decision-makers are making more decisions with less preparation and less time for thought.
As Hammes explains it, the reliance on PowerPoint often means that battle orders are rendered in incomplete, often unclear sentences and maps are squashed and stripped of meaningful detail, leaving essential battlefield questions of geography dangerously unclear. The details are classified, but Hammes told me that he has seen war plans for the Korean peninsula prepared in PowerPoint in which massive terrain issues were completely glossed over. On the whole, Hammes told me, the rise of PowerPoint in the military has made the decision-making process less intellectually active. And Tufte, he added, is the master on this whole thing.
The spread of technology over recent decades has fostered a comfort with data, and an appetite for more of it, in an ever-increasing portion of the general public. This cultural shift was especially visible in the dense data displays that appeared in newspapers, and especially online, in the run-up to the 2008 presidential election. Here, too, Tuftes influence was evident. Nate Silver, who runs the political Web site FiveThirtyEight, now part of the New York Times, uses many of Tuftes maxims in the sites design. Silver told me that he tries to keep the data-ink ratio of his current site very high, meaning most of the pixels on the screen show actual numbers or data points; he also thinks of the sites design in terms of small multiples, another Tufte neologism that refers to a series of related numbers that reveal subtle differences over time. Tufte treats data like good writing, he said. You have a certain thoughthow clearly and beautifully are you conveying it?
Good design, then, is not about making dull numbers somehow become magically exhilarating, it is about picking the right numbers in the first place. Its about data that matters to you, said Dona Wong, who was a student of Tuftes at Yale in the 1980s and later the graphics director at the Wall Street Journal.
This idea is especially relevant for how the federal government measures and displays the impact of the stimulus. What are the most informative comparisons? And what, for lack of a better word, is simply chartjunk? Tufte first suggested that the recovery board rethink how the projects are ranked. Until now, they have been sorted by location, with the idea that any person could look up projects in his or her county or zip code. But whats it matter where the project is? We already know where Texas and California are, Tufte said. Geographic space helps little in this context. Always order things substantively, Tufte explained. He would like to bring in all other kinds of data sources to add context to the stimulus and track its actual effects. Soon, if Tufte has his way, Recovery. gov will display analytical graphics that measure funded projects alongside metrics like infant mortality, traffic flows, and education. After all, as he told me, understanding doesnt come from project descriptions.
Someday, the Web site might also use what has proven to be one of Tuftes more popular inventions. In his 2007 book Beautiful Evidence, Tufte introduced what he called sparklines, numerically dense, word-size graphics that show variation over time. They have since appeared on the financial pages of Yahoo! and the sports section of the New York Times. (As an example, the fluctuations of the Dow Jones Industrial Average over the course of February and March look like this: . The dramatic dip in the figure represents the March 16th panic over the nuclear disaster in Japan.)
In November 2009, Tuftes old bte noire, Microsoft, attempted to patent sparklines for use within the spreadsheets that will appear in the latest version of Excel. The notion that the company could patent an innovation that Tufte has championed for several years struck him as a great lark, and a sign of characteristic overreaching on the part of Microsoft. But for a man who clearly takes no small satisfaction in seeing his ideas adopted, even by nefarious software conglomerates, it wasnt an entirely awful development. Im happy, Tufte told me. Sparklines are everywhere else, so why not in Excel too?
The underlying philosophy behind sparklinesand, really, all of Tuftes workis that data, when presented elegantly and with respect, is not confounding but clarifying. (Click here see an example). There is no such thing as information overload, Tufte says at the start of his courses. Only bad design. (In Portland, this last line received some applause, as well as a cry of God, yes!)
As Richard Grefe, the executive director of the American Institute of Graphic Artists, which awarded Tufte its highest medal in 2004, explained, Tufte has shifted how designers approach the job of turning information into understanding. Its not about making the complex simple, Grefe told me. Its about making the complex clear.
Tufte was born in 1942 in Kansas City, Missouri. His mother graduated high school at the age of thirteen, and four years later she became the first female reporter at the Omaha World-Herald. His father was an engineer, and Tufte remembers his parents marriage as the first sign that words and numbers belong together.
He studied statistics at Stanford and then went on to get a doctorate in political science at Yale. In 1967, he took a job teaching at Princeton. While there, Tufte was asked to give a course on statistics to a group of visiting journalists and, in looking for examples to include in the course packet, quickly became dissatisfied with the available primers on how to represent data. They were either too shallow and unserious or hopelessly arcane. He began to write up some ideas of his own.
A few years later, Tufte moved to Yale. He became friendly with Inge Druckrey, a German-born designer and teacher who had studied in the 1960s at the Basel School of Design in Switzerland, then an incubator for modernist style. The two would talk about design theory, and Tufte would visit Druckreys classes to critique student work. Before long, the two began dating.
Soon, Tuftes notes on information design had grown into a book-length manuscript. He showed it around to publishers, who insisted on redesigning many pages in the book, and imagined it as a niche title, only worth printing a couple thousand copies. Frustrated, Tufte took out a second mortgage on his home at 18 percent interest to print the book himself. He spent most of the next summer with a book designer named Howard Gralla. The two of them sat side by side in Grallas apartment, eating bagels and rearranging text so words and images would be woven together on the page. Self-publishing, Tufte told me, allowed for an incredible, bizarre fussiness.
The Visual Display of Quantitative Information came out in April 1983. To save costs, Tufte told the printer to bind only half of the initial print run of 5,000 copies. The book is now in its twentieth printing, and is one of the most successful self-published books of all time.
As one of his close friends, the psychologist and author Paul Ekman, told me, Tufte is a profoundly unconventional fellow. During those years in New Haven, Tufte would leave daily memos for his staff in a shoe box. One day, when he had been dating Druckrey for some time, his office manager came in to work, opened the shoe box, and saw a piece of torn paper that said, Find out how to get married. Druckrey was taken with Tuftes intensity. He was endlessly curious, she told me. He has this special eye and judgment, and was beaming with ideas. In 1985, they married.
If Tuftes first book was a critique, his second was a manifesto. Envisioning Information, published in 1990, implored readers to think of information design as a discipline that encompassed far more than the charts, tables, and other purely quantitative forms that had traditionally dominated the field. Graphics arent just useful for displaying numbers, in other words, but for clarifying just about anything one person is trying to tell someone else. The book opens with a print of a visitors guide to the Ise shrine in Japan and ends around 120 pages later with Galileo Galileis drawing of the rings of Saturn from 1613.
Galileo is Tuftes greatest inspiration as a designer. He is the best visual thinker ever, the best graphic designer ever, Tufte once told me. During his courses, he pulls out an original copy from 1613 of Galileos Istoria e Dimostrazioni Intorno Alle Macchie Solari from a duffel bag, and opens it to a page with a passage describing Saturn and its rings. In the book, Galileo uses words and drawings laid out next to one another to show how the planet appeared on different nights. (The shape of Saturn is thus as shown by perfect vision and perfect instruments, Galileo writes, but appears thus where perfection is lacking.) It is the same idea that showed up almost 400 years later in Tuftes sparklines.
Galileo faced the same display issues, and I want to see how he solved them, Tufte said one day in his library at his home in Connecticut. In doing research and making prints for his books, Tufte has insisted on working only from original documents, which has made him a rather prolific collector. In one visit to his library, Tufte showed me a Victorian book diagramming popular dance steps of the time, a sketchbook made by Pablo Picasso during his Paris years, and a copy of the Hypnerotomachia, a dreamlike love story that was printed in Venice in 1499, which Tufte bought at auction for $385,000. On another shelf was a first edition of Starry Messenger, Galileos book from 1610 that was the first to rely on observations from a telescope (which Tufte has since sold). It is a reminder to be better, to work harder, Tufte said.
Tuftes books feel unattached from any time or place. They are anachronistic in their images, styling, and soft-beige paper, as if dropped into the present from a vague and altogether more genteel past. A woman in the audience at his course in Seattle said that when she first saw Tuftes books she thought they were college textbooks long out of print; another man told me his friends at work had assumed that guy named Edward Tufte was British and died years ago.
After the publication of Envisioning Information, Tufte decided, he told me, to be indifferent to culture or history or time. He became increasingly consumed with what he calls forever knowledge, or the idea that design is meant to guide fundamental cognitive tasks and therefore is rooted in principles that apply regardless of the material being displayed and the technology used to produce it. As Tufte explains it, basic human cognitive questions are universal, which means that design questions should be universal too. I purposely dont write books with names like How to Design a Web Site or How to Make a Presentation, he told me.
This attitude puts him in opposition, at least in his own mind, to much of the contemporary design world. As Tufte sees it, graphic design has become a tragic field, a rich and storied craft knowledge that has been taken out of the realm of nonfiction, as he calls it, and into that of fiction, or marketing and propaganda. He told me several times of his contempt for commercial art, the graphic design that is part of a fashion and a style and will be different someday. Most designers, he said, want to do something new each time. But Im interested in the solved problem, he said. Im interested in high art and real science.
Some designers have questioned whether Tuftes reverence for elegance and accuracy can verge on dogmatism, with too little consideration of context or audience. The world is not filled with professional statisticians, said Donald Norman, the codirector of the Segal Design Institute at Northwestern University and the author of The Design of Everyday Things. Many of us would like a quick glance just to get a good idea of something. If a graph is made easier to understand by such irrelevancies as a pile of oil cans or cars, then I say all the better. (Tufte deflects this criticism by pointing out that Norman has been a paid consultant to Microsoft; Norman says his consulting work has nothing to do with his own thinking and writing.)
But when Tufte feels sure of somethingwhich is to say, quite oftenhe can have little interest in entertaining criticism. There are some people who have reached a certain position in life and will be amused and interested in a contrary opinion, and have a scholarly banter about it, said Christopher Pullman, who taught in the design program at Yale on and off since the 1960s. But thats not Tufte.
After decades of battling over the proper use of two dimensional space, Tufte has turned much of his attention in recent years to a new undertaking: outdoor sculpture. It is perhaps no coincidence that he called his first piece, made in 1997, Escaping Flatlanda name that not only describes the works bending waves of stainless steel that jut out from the ground, but also evokes a sort of personal emancipation. So much of what I did before was a war against stupidity, he told me not long ago. With sculpture its just about private pleasure.
A couple of years ago, the Aldrich Museum of Contemporary Art, not far from Tuftes house in Connecticut, invited him to put on a solo exhibition of his work, which mainly consists of abstract pieces built at extremely large scale. On to the fourth career, Tufte joked with friends. The exhibition ran until the spring of 2010; then, in April, Tufte signed a lease for an empty gallery space on West Twentieth Street in New Yorks Chelsea arts district to continue showing his work. One day over the summer, Tufte was in the gallery making some final adjustments. One long, crane-necked metal sculpture wasnt quite catching the light, and a piece that looks like a cartoonish lunar module had to be shifted so it was more visible through the gallerys picture windows.
Tufte had just returned from Washington. Pro bono consulting for government has meant a rather noticeable lifestyle changein the past, when Tufte traveled to Washington to teach his courses, he stayed at the Hay-Adams, a stately hotel on Lafayette Square, just across from the White House. Now the government puts him up at the Crowne Plaza across the river in Arlington, Virginia, which, as Tufte described it, seems to be largely populated by fifteen-year-olds from North Dakota. He showed me his GSA Smart Pay Travel Card, the government-issued credit card that federal employees and contractors use to pay for expenses. Soldiers have them, too, he said, his voice buoyant and proud. He laughed. But it comes with stern prohibitions about the minibar.
So far, Tuftes most visible contribution to Recovery.gov is a map that he designed, which shows the rollout of 101,236 stimulus projects between February 2009 and December 2010 as a proliferating series of white lights overlaid on top of a nighttime map of the United States. Tufte has been pushing Devaney and the board to do more with the data it collects and faster. But acquainting Tufte with the slow, procedural pace of bureaucracy has been the greatest challenge, Devaney told me. Tufte drives race cars, Devaney said, and most people in Washington drive tanks.
We took a walk around the gallery, stepping past a large, bemused-looking fish cast in divoted shiny metal. Tufte started telling me about the official appointment letter that he was issued by the White House. It is an ornate and formal document, with the presidents signature in the lower left corner. Soon after receiving it, Tufte took it to a frame shop near his house in Connecticut. The framer came back with a proposal. Its too square, he told Tufte, not at all the sort of golden rectangle that artists and designers tend to favor. Perhaps he could cut a few inches here and there to make it look more presentable in the frame? Tufte politely declined. Thats the very reason Im here! he told me, laughing. To fight against decoration replacing precious substance.”
