3259	write_graphviz requires more concepts than the documentation states	anonymous	Andrew Sutton	"I wanted to use write_graphviz with my custom graph adapter that
implements VertexListGraph as well as IncidenceGraph.
The documentation states, that write_graphviz only requires a
VertexListGraph. But inside, it uses an edge_iterator, and calls
edges(g), both of which belong to the EdgeListGraph.

This discrepancy was confirmed at the boost mailing list.

First, the documentation should be updated. 

But then I would also suggest to provide a second specialization for IncidenceGraph that calls out_deges() for each vertex instead of edges().

When I find time, I will prepare some code for my proposal."	Bugs	closed	Boost 1.41.0	graph	Boost 1.39.0	Problem	fixed
