A Treemap is a visualization tool used to display hierarchical data as nested rectangles. Each rectangle represents a category, with its size corresponding to a specified metric, making it easy to compare the proportions of each part within the whole.

How to Read the Visualization
The Treemap displays data as a collection of nested rectangles. The size of each rectangle is proportional to the value it represents, and rectangles are arranged hierarchically. Colors can be used to further distinguish between different categories.
