What is a Treemap?

Treemaps essentially show parts of a whole. They display hierarchical information as a cluster of rectangles varying in size and color, depending on their data value. The size of each rectangle represents a quantity, while the color can represent a number value or a category. Treemaps allow you to view trends and make comparisons quickly.

When to use a Treemap?

Treemaps are one of the most compact and space-efficient options for displaying hierarchies and are also great at comparing the proportions between categories via their size. A well-designed treemap makes patterns, trends, relationships, and clusters visible in seconds.

Best Practices for Creating Treemaps

  • Label each region appropriately with text or numbers.

  • Use bright, contrasting colors, so each region is easily defined.

  • Avoid labeling every box if you have a lot of data.

  • Don’t clutter your treemap with too many boxes – treemaps can contain any number of boxes, but space is limited! You don’t want your treemap to be hard to read.
