The following is a heat map that shows the same information, but in matrix form. It’s a little easier to compare transitions between two edges, but is less useful to understanding the network formed by the transitions.

These graphs were created for a talk that Shane Sanders and I conducted at the Midwest Sports Analytics Meeting 2018.

I then averaged each minute to come up with this visualization:
