Pie chart

Pie charts show part-to-whole relationships. They’re best for showing coarse relative size across categories.

  • Show 7 slices max, biggest one first.
  • Align the main piece so it starts at 12 o’clock.
  • Make sure it adds up to 100%! If there’s data missing, show it as “uncategorized” or “other.”
  • Pair data with interpretation.
  • Don’t show multiple pies.
  • Use a pie, not donut-style chart.
