About the Pie chart maker

Values, not percentages

Type the raw numbers (visits, votes, hours) and the chart works out each slice. They do not need to add up to 100.

Readable charts

Pie charts work best with up to six slices. Group small ones into "Other", or use the bar chart maker for longer lists.

Frequently asked questions

Do the numbers need to add up to 100?
No. Each slice is sized by its share of the total.
Can I use decimals?
Yes, values such as 12.5 work.
Is my diagram uploaded?
No. It is drawn in your browser.
