I did and get to play with the queries for a while. the result is stunning. If I create some nice Script that will get all the resources I will have a great overview.
The problem I have with resource-graph atm is that it uses AzGraph, Google teached me that AzureRMGraph is only in preview (to download the module it is still a pain in the ..
Don't know if it's an issue but All my preview commands and modules used the AzureRm. Always got the perception that AzureRM vs Az is the Resource Manager vs Classic aka the new vs the old way of working. That's why I need to make sure I don't create the script and change it one Az becomes not available.
