Yesterday, Chartporn posted a link to an OkCupid post about sex, specifically charts of sex. And yes, they are quite interesting and worth checking out. But, I enjoyed the humour at the outset, where they noted the brilliance of the pie chart as a modern chart form that can replace the classic Minard chart about Napoleon’s invasion of Russia.
Minard’s original at top, the modern simplification at bottom.

Credit for the work to OkCupid.
