Visualize the graph

Now that we've thought a bit about how we constructed our network, let's size our graph and make an initial visualization. Before you make the plot, you'll calculate the number of vertices and edges. This allows you to know if you can actually plot the entire network. Also, the ratio of nodes to edges will give you an intuition of just how dense or sparse your plot might be. As you create your plot, take a moment to hypothesize what you think the plot will look like based on these metrics.
