Exercise

Visualize tie centrality

In this exercise, you will use the ggraph package again, but this time you will visualize the network by making tie size proportional to tie betweenness centrality.

Can you visually spot the central ties in the network topology? Recall that high betweenness ties typically act as bridges between different communities of the network.

Next, we will add degree centrality to visualize important nodes.

The network g is already loaded in the workspace.

Complete the plotting code. Add an edge link geometry, mapping the tie transparency to tie betweenness.
Look at the plot. Where are the most important chains of relationships?
