Treemaps are one of the most compact and space-efficient options for displaying hierarchies. They are also great at comparing the proportions between categories via their size. They allow the viewer to see trends and make comparisons quickly.
The information is usually displayed in rectangles. When the color and size dimensions are organized in this tree-like structure, it’s easier to see patterns that one couldn’t identify by simply looking at the raw data. Treemaps also make efficient use of space, making it possible to display thousands of data points on one screen.
This article covers the basics of where to use interactive treemap charts, the types of charts Infogram offers, how to get started, and frequently asked questions. Don’t worry, we’re handling the complicated technical pieces, allowing you to focus on creating engaging, exciting, and educational content that will delight your customers.
Where to use an interactive treemap
Treemaps essentially show parts of a whole, and how everything is divided. 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. Simultaneously, they also show how data is organized.
Treemaps are best used when there is a large amount of data to share. Global populations organized by countries or statewide voting records organized by county would greatly benefit from a treemap.
If the data is very balanced, a treemap is not recommended; it works best with more varied data points. It’s recommended to use an interactive treemap when there are more than two or three levels of organization to display.
