Completed the D3js Treemap Diagram project. Feedback please!

Here is my 5th D3js and the first Treemap project, another hard project (for me at the moment since it’s my first treemap feeling I’m totally new here). Happy to learn with the freeCodeCamp.

Need your valuable feedback for any development.

Thank you.
