graphToDot :: Graph gr => gr a b -> [Attribute] -> (LNode a -> [Attribute]) -> (LEdge b -> [Attribute]) -> DotGraphSource
Convert a graph to dot format. You can then write this to a file and run dot on it
graphToGraph :: forall gr a b. Graph gr => gr a b -> [Attribute] -> (LNode a -> [Attribute]) -> (LEdge b -> [Attribute]) -> IO (gr (AttributeNode a) (AttributeEdge b))Source
Run the graph via dot to get positional information and then combine that information back into the original graph
