QuickGraph supports MSAGL to render the graphs. The QuickGraph.MsAgl assembly contains specialize 'populator' that convert a QuickGraph graph into a MSAGL graph.

IVertexAndEdgeListGraph<string, Edge<string>> g = ...;

var populator = MsAglGraphExtensions.CreateMsaglPopulator<string, Edge<string>>(g);
populator.Compute();
Graph g = populator.GleeGraph; // we have the graph :)

Once you have the Glee graph, you can use the MSAGL rendering support or built-in visualizer control to view it.

Hook to the VertexAdded, EdgeAdded events to get a hold on the MSAGL nodes and edges as they are created.

WARNING: You must have a copy of MSAGL in order to get this to work!
