This PR is still a draft and needs improvement. Only uses statistics functions to create network plots by including scripts from @bobbyxng, @FabianHofmann and me.

Feel free to make improvements/changes to make it even more modular.

this looks nice @p-glaum, what is the status? can I support with something?

status hasn't changed so far :sweat_smile: . It was just an initial draft, that the code is not lost/forgotten. I think it still needs some cleaning and updating because not all graphs look nice at the moment. I collected some TODOs above. Currently, I don't have the time to continue on this. @bobbyxng was also working on this, but I think he is currently also busy. So if you want, you can go ahead with the implementation :)
