Frequently asked questions

Difference from a pie chart?

Visually a ring instead of a filled circle. The data and computation are identical — see the <a class="underline" href="/pie-chart-maker">Pie Chart Maker</a>.

Can I put a label in the middle?

Download the PNG and overlay your KPI in your slide tool — keeps this tool dependency-free.

Why no per-slice legend value?

Hover the slices in the live preview to see the value — the PNG export keeps it clean by default.
