Pie Chart Maker

A pie chart shows how a whole splits into parts — a budget, survey answers, market share or time spent. Paste labels and values, and this maker draws a clean pie or donut chart with percentages, values or names on the slices and a legend beside or below it. It runs in your browser and gives you a PNG for documents and slides plus an SVG you can scale or edit.

How to use this tool

1. Enter one "label, value" line per slice, or paste two columns from a spreadsheet.
2. Add a title, choose a donut hole and what each slice should show.
3. Set the legend position, order, colours and the start angle; optionally group tiny slices into “Other”.
4. Set the size and resolution, then download the PNG or SVG.

Formula

Share = value ÷ total; Angle = share × 360°

Slices start at 12 o’clock (or your start angle) and run clockwise in the order shown. Each slice edge is drawn from cubic Bézier curves of at most 90°, which match a true circle to within 0.03% of the radius. Labels that would not fit inside their slice are left to the legend, and zero values are skipped because they have no area.

Example

A budget of Rent 1,200, Food 450, Transport 180, Savings 400 and Fun 220 totals 2,450. Rent is 1,200 ÷ 2,450 = 49.0% of the pie, a 176.3° slice, while Transport is 7.3% (26.4°). With values 25, 25 and 50, the slices are exactly 90°, 90° and 180°.
