Pie charts are overrated

Quoting Seth’s Blog: How to make graphs that work:

Pie charts are spectacularly overrated. If you want to show me that four out of five dentists prefer Trident and that we need to target the fifth one, show me a picture of 5 dentists, but make one of them stand out. I’ll remember that.

Unless, of course, all you want to do is give a sense of all different percentages.
