Edward Rolf Tufte (pronounced /ˈtʌfti/) (born 1942 in Kansas City, Missouri, to Virginia and Edward E. Tufte), a professor emeritus of statistics, information design, interface design, and political economy at Yale University^[1] has been described by The New York Times as "the Leonardo da Vinci of Data".

He is an expert in the presentation of informational graphics such as charts and diagrams, and is a fellow of the American Statistical Association. Tufte has held fellowships from the Guggenheim Foundation and the Center for Advanced Study in Behavioral Sciences.

Tufte lives in Cheshire, Connecticut. He periodically travels around the United States to offer one-day workshops on data presentation and information graphics.

Tufte's writing is important in such fields as information design and visual literacy, which deal with the visual communication of information. He coined the term "chartjunk" to refer to useless, non-informative, or information-obscuring elements of quantitative information displays.

He uses the term data-ink ratio to argue against including non-informative decoration in visual displays of quantitative information. He claims that ink should only be used to convey and display significant data. In chapter 2 of The Visual Display of Quantitative Information, Tufte states:

“

Sometimes decorations can help editorialize about the substance of the graphic. But it's wrong to distort the data measures—the ink locating values of numbers—in order to make an editorial comment or fit a decorative scheme.

”

Tufte has criticized the way Microsoft PowerPoint is typically used. In his essay The cognitive style of PowerPoint, Tufte criticizes many properties and uses of the software:

• Its use to guide and reassure a presenter, rather than to enlighten the audience;
• Unhelpfully simplistic tables and charts, resulting from the low resolution of computer displays;
• The outliner causing ideas to be arranged in an unnecessarily deep hierarchy, itself subverted by the need to restate the hierarchy on each slide;
• Enforcement of the audience's linear progression through that hierarchy (whereas with handouts, readers could browse and relate items at their leisure);
• Poor typography and chart layout, from presenters who are poor designers and who use poorly designed templates and default settings;
• Simplistic thinking, from ideas being squashed into bulleted lists, and stories with beginning, middle, and end being turned into a collection of disparate, loosely disguised points. This may present a kind of image of objectivity and neutrality that people associate with science, technology, and "bullet points".

Tufte's criticism of PowerPoint has extended to its use by NASA engineers in the events leading to the Columbia disaster. Tufte's analysis of a representative NASA PowerPoint slide is included in a full page sidebar entitled "Engineering by Viewgraphs" [1] in Volume 1 of the Columbia Accident Investigation Board's report.

Index	Day	Value	Change
Dow Jones		10765.45	−32.82 (−0.30%)
S&P 500		1256.92	−8.10 (−0.64%)
Nasdaq		2244.83	−13.97 (−0.62%)

Tufte also developed sparklines — a simple, condensed way to present trends and variation, associated with a measurement such as average temperature or stock market activity. These are often used as elements of a small multiple with several lines used together.

Tufte's Yale PhD thesis was The civil rights movement and its opposition (1968).

Early in his career, Tufte wrote several books about using statistics to analyze political issues:

• Dahl, Robert; Edward R. Tufte (1973). Size & Democracy. Stanford University Press. ISBN 0804708347. 
• Tufte, Edward R. (1974-08-05). Data Analysis for Politics and Policy. Prentice Hall College Div. ISBN 0131975250. 
  • Tufte notes on his website that a second edition of this book is likely.
  • Tufte now owns the copyright and has made a free pdf of DAPP available on his website.
• Tufte, Edward R. (1978). Political Control of the Economy. Princeton University Press. ISBN 0691075948. 

The core of Tufte's work documents how to best display different forms of information with copious examples and commentary:
