This is only the best infographic of all time, and it was made by a man named Charles Joseph Minard. To quote from Tufte:
Probably the best statistical graphic ever drawn, this map by Charles Joseph Minard portrays the losses suffered by Napoleon’s army in the Russian campaign of 1812. Beginning at the Polish-Russian border, the thick band shows the size of the army at each position. 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.
My co-worker just gave me this poster, free of charge. It is now displaying in my cubicle, directly to my right.
I am very happy.
