Use it when
- 2–4 categories that sum to a meaningful 100%
- When one slice clearly dominates
- A quick, familiar split for non-technical viewers
Avoid it when
- More than 4 slices — angles are hard to compare
- Comparing pies to each other
- Anything where ranking matters (use a bar)
Common mistakes
- 13D pies (distort everything)
- 2A rainbow of near-equal slices
