python 3.x - Simulating Network flows in NetworkX -

-

i trying simulate network flow problem in networkx each node constrained capacity. need specify demand rates , capacity @ every node (also ensure flows don't exceed capacity). of now, have defined flows edge weights.

is there way in networkx? if so, modules, should using? nice if visualize network simulation. simple code involving 4 or 5 nodes lot.

thanks.
