Histogram Plots key error

[M-Lampert]

I am currently going through the tutorial that explains how to implement your own plot function. It uses a histogram plot as an example that should be usable with pp.plot(graph, kind="hist"). However, in the current pathpyG version, this method throws a KeyError (see StackTrace below). It seems that only part of the functionality is implemented. There is a file hist_plots.py in the visualisations-module but none of the submodules for a specific backend contain a similar file. It seems to me that the tutorial mentioned above stops at the same part where also the implementation is missing.

Is this intended this way? Do we want the histogram plots to be part of our visualisation-functionality or is this only meant for educational purposes? Then we should maybe remove the implementation and make it clear in the tutorial that this functionality does not exist and is only meant as an example.

StackTrace:

I will check the code. Probably it is the best to remove this particular tutorial for now. In the long run it is intended to use the plotting backend to plot different types of plots including histograms, scatter plots, alluvia plots,...
