A few months back, I received a mailer about a one-day course on “Presenting Data and Information” that was being taught by Edward Tufte and while I didn’t go to the class, one of the graphics that it contained really impressed me and I’ve been meaning to post it ever since (click on the thumbnail to launch a popup that contains a larger image):
“This map drawn by Charles Joseph Minard portrays the losses suffered by Napoleon’s army in the Russian campaign of 1812. Beginning at the left on the Polish-Russian border near the Niemen, the thick band shows the size of the army (422,000 men) as it invaded Russia. The width of the band indicates the size of the army at each position. In September, the army reached Moscow with 100,000 men. The path of Napoleon’s retreat from Moscow in the bitterly cold winter is depicted by the dark lower band, which is tied to temperature and time scales. The remains of the Grande Armee struggled out of Russia with 10,000 men. Minard’s graphic tells a rich, coherent story with its multivariate data, far more enlightening than just a single number bouncing along over time. Six variables are plotted: the size of the army, its location on a two-dimensional surface, direction of the army’s movement, and tempreature on various dates during the retreat from Moscow. It may well be the best statistical graphic ever drawn.”
Okay, impressed yet? Here is a bit more about Mr. Tufte. Edward Tufte is Professor Emeritus at Yale University, where he taught courses in statistical evidence, information design and interface design. He has written several books, which have won 40 awards for content and design. The NY Times has called him “The Leonardo da Vinci of data.”
Still not impressed? Then try reading this essay which was published in Wired about how PowerPoint affects thought. It will blow your mind. I highly suggest you read it if this topic interests you at all because he is to data what Stephen Hawking or Brian Greene is to physics.
One of my goals this year is to read as many of his books as possible. Wish me luck.
