Hope you are doing well. Filter unanswered questions and find this thread. I am late but might be helping for someone in future.
I paste the image of tree map with sample data. You can share sheet or you can export image as well.
No Code Data Visualization Tool used for this chart. 50+ advance chart library.
You can check here for Microsoft Excel & Office 365.
And if you are comfortable with Google Sheets, you can find here.
