tekore VS pyfactor

I've written one for Spotify. Not sure if you're after example implementations or a specific client, but in case of the former, have a look at Tekore. It has complete OAuth2, automatically refreshing tokens, async with one switch and output parsed to Python objects.

Enumeration: collection of accepted values, so for example a function could accept an enumeration type instead of strings to make sure the value is in some predefined set of valid ones (example)

Data storage, i.e. dataclass: a collection of attributes making up some cohesive data unit, sometimes without any extra methods, so you can group information and avoid multiplying the numer of function parameters (example)

You're absolutely right! It does serve as a proxy for a certain type of complexity, but as you said, everything can be hidden in a single inner scope. Particularly with imports and nested modules, the graph becomes quite messy and fast. But there has been a request for choosing the level of analysis!

You can find more examples of popular libraries in our RTD gallery, or try it out on your own sources by installing on PyPI. The code is on GitHub. Fresh additions to the library are docstring tooltips, waypoint node and bridge analysis (the purple nodes and red edges), and collapsing waypoint nodes for removing detail. Thanks to u/dd2718 for the awesome suggestions!

That's coming! And actually being able to visualise importable packages simply by name would be nice too, at least once we figure out the details. Much appreciated!
