Great - this can be achieved easily with Sinkhorn-Knopp balancing.

Thanks. Do you know if something similar holds in an undirected weighted graphs when the sum of vertex weights of each node is equal?

@GitGud In real life, it seems to me that there is a difference between defining what an object is by describing the object itself and defining what an object is by describing how it is generated. I just don't know if this distinction makes sense in math.
