I have a bunch of kind 3 events lying around and used two different methods to visualize the resulting contact list graph.

One is used for the coloring (Louvain) - don’t ask me, why or how it works, but it looks cool.

The other is for the distances between contacts (force direction). Basically it makes contacts repell each other but following relations attract each other, so that in the end subgraphs with a lot of internal followings will cluster.
