Annotating Node Labels on Matrix Plots.

for n, d in G.nodes(data=True):
G.nodes[n]["group"] = randint(0, 3)
G = nx.relabel_nodes(G, {i: "long name #" + str(i) for i in range(len(G))})
fig, ax = plt.subplots(figsize=(10, 10))
nv.matrix(G, group_by="group", node_color_by="group")
annotate.matrix_labels(G, group_by="group", layout="standard")
# the standard labels take up more space, so we will have to increase the
# padding a bit. 5% on all sides works well here.
