CircosPlot with networkx 2.4 (group_labels)

• networkx version: 2.4

• Operating System: Windows

Description

Hey, so. I upgraded my networkx today to 2.4 and since the CircosPlot group_label parameter stopped working.
It was giving me an error on line 821, saying that "Graph doesn't have node" because of

[self.graph.node[n][self.node_color] for n in self.nodes])))

What I Did

I was able to solve it by tweaking the function in plots.py to the following:

sorted(list(set([list(self.graph.nodes.values())[n][self.node_color] for n in np.arange(len(self.nodes))])))

Now it works fine!! Legend for groups is generated fine!

Not sure if anyone else had this problem, but in case.. here is a possible solution!!

@eduardacenteno thanks a ton - yes, this is the correct fix.

Would you be open to submitting a PR to the library?

I've been gradually upgrading all of my NetworkX projects to v2.4 with this breaking change, but haven't had the bandwidth yet to make it over to nxviz.

Sure, I'll fork it and submit a PR with the corrected version :)
