User is able to create the tree map chart but when it is shared between two users (the excel document), the graph does not display and gets an error. all users have the same version of office 365 excel 2016 (same build and same version of windows)
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.
Thanks
