Charles Joseph Minard

Minard's flow map of Napolean's march

This is a map drawn by Charles Joseph Minard depicting the losses suffered by Napolean’s army in the Russian invasion of 1912. It depicts several variables – size of the army, 2D location, direction of army’s movement and temperature on various days. It is considered one of the best statistical graphs ever drawn. Amazing!
