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 visualization—the 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.

“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 Moscow—to the right, on the map—they begin to die, and the stripe narrows.
