I am not terribly familiar with the write_graphviz interface, so this may
not be too helpful. I believe the problem is the manner in which setS and
vecS identify vertices (descriptors) in the graph data structure. You may
need to provide a vertex index map when you call write_graphviz, possibly
using dynamic_properties. Unfortunately, I don't have any examples to point
at. Perhaps other users will have encountered and solved the same problem.
