Comment (by chapoton):
Replying to [comment:3 dcoudert]:
> Small modification to allow loops in directed graphs.
* It would be better if the examples given check something else than the
fact that the number of vertices is correct. One can for example count the
edges.
* Maybe remove the plot in the examples, which has not much to do there.
* Maybe check the commutativity of the product
* Maybe it would be good to have a test with loops ?
