Describe the bug

In StellarGraph, some algorithms are in demo notebooks or scripts, without being listed in our main documentation. This could mean that a user reading our docs thinks they're not supported in StellarGraph.

• nxviz version: 0.6.1
• Python version: 3.7.4
• Operating System: Linux

Description

The following example doesn't work with networkx 2.4 :

from random import choice

import matplotlib.pyplot as plt
import networkx as nx
from nxviz.plots import CircosPlot

G = nx.barbell_graph(m1=10, m2=3)
for n, d in G.nodes(data=True):
    G.nodes[n]["class"] = choice(["a", "b", "c",

Similarly to DeepGraph.plot_2d and DeepGraph.plot_2d_generator, implement plot_3d and plot_3d_generator

This is not really a bug but rather a workaround that I wanted to make available for others (and maybe you want to integrate it at some point into the library itself).

I wanted to color all nodes by a node property. It is possible to achieve this by using the coloring by `group'. One only has to assign each node an html color according to its value.

Below I give a minimal example that colors
