When a pie chart works

Keep the chart simple enough to read.

Pie charts work best when a small number of categories make up one meaningful total. The editor helps you see the total, percentages, and tiny slices before you export.

01

Use 3 to 6 slices

Readers compare angles less precisely than bars. A short category list keeps the important differences visible.

02

Order with intent

Put the most important or largest category first, then use a consistent clockwise order in the final chart.

03

Combine tiny categories

Slices below roughly 3 to 5% are difficult to label. Group them into “Other” when the detail is not essential.

Syntax Pattern

Mermaid pie chart syntax

Mermaid pie charts begin with the pie keyword, can include a title, and use a quoted label followed by a positive value for each slice.
