Câu hỏi thường gặp
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.
