Plantuml can also generate ASCII, so playing with ditaa I managed to have intersting things...

I opened a public repo on my GitLab account to put that all so you can have a visualization of it (source files and `png`s):

`dot` files seems also interesting by the way...


There is a PlantUML Sphinx extension (which requires Java):
https://github.com/sphinx-contrib/plantuml/

There is GraphViz Sphinx extension:

It looks like pyreverse can generate UML diagrams as DOT files:
https://github.com/PyCQA/pylint/tree/master/pylint/pyreverse

IDK how much post-processing or tool customization is necessary to implement the requested UML diagram styles.

This generates DOT files from Django model classes (without adding a Java dependency to the Sphinx docs build):

This generates PlantUML and DOT diagrams from SQLalchemy classes:
