Using a Tree Map as a Legend in Power BI

Prathy Kamasani makes clever use of a tree map:

I recently worked on two projects where the client wanted to show multiple metrics sliced by the same categorical data. For example, seeing how various metrics are performing over different regions or different product groups. A use case like this can be achieved in many ways; probably the best approach is to use small multiples functionality or to keep it simple, five same visuals with different metrics.

Let’s look into it with energy consumption data. Here, I want to show metrics 1 to 5 on different income levels over the years.

I like this solution when you have multiple graphs off of the same base data, like in the small multiples scenario Prathy shows us.
