Nested Rectangle Chart

A Nested Rectangle Chart, can be thought of a basic Treemap, is ideal for visualizing hierarchical data. It uses nested rectangles to represent different categories and subcategories, making it easy to see the relative size of each part within the whole. 

How to Read the Visualization 

The Nested Rectangle Chart displays data as a series of nested rectangles. Each rectangle represents a category, and its size is proportional to the value it represents. Subcategories are shown as smaller rectangles within the larger ones, allowing for a clear hierarchy. 

Data Structure 

• Measures: 1 or more 

• Dimensions: 1 or more (with hierarchical levels) 

Best Practices / Limitations 

• Hierarchy: Best used for data with a clear hierarchical structure. 

• Clarity: Ensure rectangles are not too small to read; consider combining smaller categories. 

• Color: Use color to differentiate between categories and subcategories.
