Pie Charts Considered Harmful

Note that seaborn doesn’t create pie charts, as seaborn’s author considers those to be unfit for statistical visualization. See e.g. Why you shouldn’t use pie charts – Johan 1

Why you shouldn’t use pie charts:

Pies and doughnuts fail because:

  • Quantity is represented by slices; humans aren’t particularly good at estimating quantity from angles, which is the skill needed.
  • Matching the labels and the slices can be hard work.
  • Small percentages (which might be important) are tricky to show.
