EDWARD ROLF TUFTE

is an American statistician and professor emeritus of political science, statistics, and computer science at Yale University. He is noted for his writings on information design and as a pioneer in the field of data visualization. Tufte is an expert in the presentation of informational graphics such as charts and diagrams

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. Other key concepts of Tufte are the lie factor, the data-ink ratio, and the data density of a graphic.

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 also encourages the use of data-rich illustrations with all the available data presented. When examined closely, every data point has value; when seen overall, trends and patterns can be observed. Tufte suggests these macro/micro readings be presented in the space of an eyespan, in the high resolution format of the printed page, and at the unhurried pace of the viewer’s leisure.

The classic book on statistical graphics, charts, tables. Theory and practice in the design of data graphics, 250 illustrations of the best (and a few of the worst) statistical graphics, with detailed analysis of how to display data for precise, effective, quick analysis.
