DrawNetwork displays the vertices, arcs and vertex labels of a network. A network is a directed graph with at least one vertex with indegree 0 (the source) and at least one vertex with outdegree 0 (the sink).

If you specify S and T, the graph is displayed with S as the main source and T as the main sink.

The network can be displayed either horizontally or vertically.

Remaining options are passed on to the DrawGraph command.
