I've done some class diagramming with erdantic. It's pretty limited but it's pretty easy to access and diagram out classes quickly in .png form.
However, I'm looking for something higher level, so I can diagram an entire module. I looked into doxygen's ability to diagram but I think its limited to C++ according to the documentation I read (and linked above).
Is there any other standard tool that can do this?
** p.s. yes I tried pycharm which is handy for class diagrams, but I'm really looking at something that can diagram from the modular level.
