is there a way to graph the imports within a Python module?

Question

I'm trying to understand the structure of a medium-sized Python project (10ksloc) while planning at refactor. Are there any utilities that have at least the following feature:

• Running said utility generates a graph of just the module-level import relationships

Additional features that would be nice to have:

• explanation of where an import relationship comes from (eg "imported a.SomeClass at b.py:2")
• filtering out modules from standard library
• filtering out modules installed to site-packages
• some level of interactivity, like with flamegraph.pl's SVG output
• exporting to DOT format for further visualization opportunities

I understand that this functionality must exist for projects like pyinstaller to work under the hood (how else would you do hook discovery?), but haven't seen anything from my searches.

If there's nothing like this, how would you build such a feature with the last module?
