Record each node's degree centrality score in its node metadata.
Do this by assigning nx.degree_centrality(G_lmc)[n] to G_lmc.node[n]['degree centrality'] in the second for loop.
Visualize this network with an ArcPlot sorting the nodes by degree centrality (you can do this using the keyword argument node_order='degree centrality').

# Import necessary modules
from nxviz import ArcPlot
import matplotlib.pyplot as plt

# Identify the largest maximal clique: largest_max_clique
largest_max_clique = set(sorted(nx.find_cliques(G), key=lambda x: len(x))[-1])

# Create a subgraph from the largest_max_clique: G_lmc
G_lmc = G.subgraph(largest_max_clique).copy()

# Go out 1 degree of separation
for node in list(G_lmc.nodes()):
    G_lmc.add_nodes_from(G.neighbors(node))
    G_lmc.add_edges_from(
        zip([node] * len(list(G.neighbors(node))), G.neighbors(node)))

# Record each node's degree centrality score
for n in G_lmc.nodes():
    G_lmc.node[n]['degree centrality'] = nx.degree_centrality(G_lmc)[n]

# Create the ArcPlot object: a
a = ArcPlot(graph=G_lmc, node_order='degree centrality')

# Draw the ArcPlot to the screen
a.draw()
plt.show()
Add nodes to G_lmc from the neighbors of G using the .add_nodes_from() method and .neighbors() methods.
Using the .add_edges_from(), method, add edges to G_lmc between the current node and all its neighbors. To do this, you'll have create a list of tuples using the zip() function consisting of the current node and each of its neighbors. The first argument to zip() should be [node]*len(G.neighbors(node)), and the second argument should be the neighbors of node.
Record each node's degree centrality score in its node metadata.
Do this by assigning nx.degree_centrality(G_lmc)[n] to G_lmc.node[n]['degree centrality'] in the second for loop.

INSTRUCTIONS
100XP
Import ArcPlot from nxviz.
Create an un-customized ArcPlot of T. To do this, use the ArcPlot() function with just T as the argument.
Create another ArcPlot of T in which the nodes are ordered and colored by the 'category' keyword. You'll have to specify the node_order and node_color parameters to do this. For both plots, be sure to draw them to the screen and display them with plt.show().
