Frequently asked questions

How many slices should a pie chart have?

Pie charts work best with 3-7 slices. For more categories, consider grouping smaller ones into an 'Other' slice, or use a bar chart instead.

Can I create a donut chart?

Mermaid's native pie chart renders as a standard pie. After export, you can modify the SVG to add a center cutout for a donut style.

When should I use a pie chart vs. a bar chart?

Use pie charts when showing parts of a whole (percentages that add to 100%). Use bar charts when comparing absolute values or when you have many categories.
