Visualize filtered graph using nxviz

Here, you'll visualize the filtered graph using a circos plot. The circos plot is a natural choice for this visualization, as you can use node grouping and coloring to visualize the partitions, while the circular layout preserves the aesthetics of the visualization.

Instructions

  • Compute degree centrality scores of each node using the bipartite module degree centralities, but based on the degree centrality in the original graph.
    • Use the nx.bipartite.degree_centrality() function for this, with the arguments G and nodes=forum_nodes.
  • Create a new circos plot with nodes colored and grouped (parameters node_color_by and group_by) by their partition label ('bipartite'), and ordered (parameter sort_by) by their degree centrality ('dc') and display it.
    • To ensure that the nodes are visible when displayed, we have included the argument node_enc_kwargs={'radius': 10}.
