Design Improvements : nested treemap

[AlmahaAlmalki]

Hi,

In the treemap, everything looks great; I love it great job guys. I only have one comment in the nested treemap. From a design prescriptive there's nothing tells me that this treemap is nested? As a user, I will see the graph thinking it's a one level treemap. I think Sanjay we can sit together and discuss different solutions 👍
