I was afraid someone would ask. It's a minimal proof of concept that I did in a day for a specific use case. It's only for directed digraphs, only stores node attributes, and has zero tests.

If you still want to poke around: https://github.com/gfleetwood/nxdb. I just added comments and renamed some variables for clarity, so there might be errors.

I would like some pointers for networkx generation for my graphdb pypi package if you wanna share some thoughts. :)

Sure. Would be glad to help if I can. My email is in my GitHub profile.

Can’t wait for networkx integration! :)
