Is it possible to make arcplot directional?

[Xiaojieqiu]

Thanks for this cool project, I just wonder is it possible to draw arrows when plotting a directional graph with arcplot?
Passing edgeprops={"arrowstyle": "->", "arrowsize": 100000,} to nv.ArcPlot doesn't seem to work.

Looks like the edges are drawn wit the following code (

nxviz/nxviz/plots.py

Line 802 in c7c9e1d

def draw_edges(self):

):

path = Path(verts, codes)
            patch = patches.PathPatch(
                path, lw=lw, edgecolor=color, zorder=1, **self.edgeprops
            )
            self.ax.add_patch(patch)

If you have any thoughts, please let me know any suggestions. Very much appreciated!

there are two possible solutions for me:

1. add an arrow to represent the direction
2. if make the edges above the node as interaction from left to right and edges below it interactions from right to left.

@Xiaojieqiu thanks for chiming in! Given how densely populated edges and arrows might become, I think your second suggestion, that is to make edges above the Arc line represent edges going from left to right, and edges below the Arc line represent edges going from right to left, makes the most sense!

Are you interested in putting together a PR for this feature? If so, please let me know. I'm going to be going offline for a few weeks, as my first kid is arriving and the company I work for is entering year-end review season, so producing code is going to be difficult, but I'll be happy to review code if you're game for it!
