Frequently Asked Questions

What is a treemap?

A treemap shows data as nested rectangles — larger rectangles represent larger values, making it easy to compare proportions at a glance.

When should I use a treemap vs a pie chart?

Treemaps work better for many categories (6+) where a pie chart becomes cluttered. They also show hierarchy better.
