Arrow Style for Directed Graphs

[Neta Livneh]

Is it possible to change the arrow style in directed graphs (something like adding an attribute for "arrowstyle", as is implemented in matplotlib https://matplotlib.org/stable/api/_as_gen/matplotlib.patches.ArrowStyle.html)?

Thanks,
Neta

Yes please, I came here to request the same thing. I'm interested in modelling entity relationship diagrams, where such endings might represent one/many/optional relationship cardinalities, and where I previously explored this in SVG, you can attach marker-end and marker-start decorations which opens up the option to attach alternate SVG widgets to line endings.

Wouldn't cross over into the 3d plots very easily though.

Looking for the same thing, has anyone looked into this?
