added to_pandas_edges_arrows to core.py which calculates portions of the line to be shown as arrows.

added draw_networkx_arrows to draw_altair.py which draws the arrows as rectangles on the lines. Added parameters:

Not dependent on my other pull request. Will require a merge to put them together, only conflict will be in draw_networkx due to the if statements.

Graphs look similar to a DiGraph in networkx base package plotting. Arrows are only appied if G isinstance nx.DiGraph.

So 1 issue, the new lines appear on top of the points. Any way to fix that?

Also, any ideas on how to make the arrows 'prettyer'? I may add a color parameter. The variable lengths look kinda trippy too, might make that parameter default to like, .1 instead.

Great! Thank you for working on this. I've been meaning to add arrows.

Sorry for the slow-ish replies! I'm traveling right now with limited internet. I'll try to review this PR more closely in the next day or two.
