Question:How do I label sources and sinks in a directed graph network?

Good day!

I wish to represent the flow across a network from a set of sources to a number of destinations or sinks.

In the simple example attached, there are 4 sources and 10 possible sinks. The flow from source to sink is given by the matrix, A, and each element is a binary entry; 1 for active and 0, otherwise. I would like to assign labels to each source (A,B,C,D) and sink (1,2,3,..., 9,10) and this feature will be most convenient for large matrices.The idea is to have these labels shown on the directed graph so that it is easy to see the flow configurations at a glance.

Does anyone know how this can be done?

Thanks in advance.
