PyPi interactive dependency graph
The graph takes a moment or two to load but is well worth the wait.
Mouse-over for popup labels.
The code is available on GitHub.
I don’t know the use case for displaying all the dependencies (or rather all the identified dependencies) in PyPi.
Or to put it another way, being able to hide some common dependencies by package or even class could prove to be helpful.
Seeing data in its aggregate isn’t as useful as discovering important data in the process of hiding common aggregate data.
