I agree strongly  that pie charts generally do not work so well as bar  
charts: that advice is much repeated in the literature.

But let's get the history straight.

Pie charts (not named as such) are due to William Playfair.

Florence Nightingale's diagrams were not pie charts, but bar charts in  
polar coordinates and not original with her: she copied the design  
from William Farr, and he was at best the fourth person to use them.
