Description: Provide modification which allow networkx to draw multiple edges between nodes
Requirement: install matplotlib and networkx packages
Installing:
copy-past the patches2 file in your matplotlib package (C:\Users\Utilisateur\Anaconda3\Lib\site-packages\matplotlib or wherever it is)
copy-past the edges file in the directory where you want to run your python program and import it (import edges as e) and import matplotlib and networkx
you can now use the draw_networkx_multi_edges and play with the rad argument to draw your graph with multiple edges as seen in the example 1
example 2 is just another example of more complicated graph draw with this function
Caveat: work only if the parameter arrows is set to true in draw_networkx_multi_edges (default settings)
