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').

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.

matplotlib.pyplot has been imported for you as plt. 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().
