Exercise

Arc plot

Next up, let's use the Arc plot to visualize the network. You're going to practice sorting the nodes in the graph as well.

Note: this exercise may take about 4-7 seconds to execute if done correctly.

Instructions

100 XP
  • Make an Arc plot of the GitHub collaboration network, with authors sorted by degree. To do this:
    • Iterate over all the nodes in G, including the metadata (by specifying data=True).
    • In each iteration of the loop, calculate the degree of each node n with nx.degree() and set its 'degree' attribute. nx.degree() accepts two arguments: A graph and a node.
    • Create the arc plot a by specifying two parameters: the graph argument, which is G, and the sort_by argument, which is 'degree', so that the nodes are sorted.
    • Display the arc plot to the screen.
