Documentation

graphToDot :: (Ord b, Graph gr) => gr a b -> [Attribute] -> (LNode a -> [Attribute]) -> (LEdge b -> [Attribute]) -> DotGraph Source

Convert a graph to dot format. You can then write this to a file and run the appropriate command on it (found using commandFor).

clusterGraphToDot :: (Ord c, Ord b, Graph gr) => gr a b -> [Attribute] -> (LNode a -> NodeCluster c a) -> (c -> [Attribute]) -> (LNode a -> [Attribute]) -> (LEdge b -> [Attribute]) -> DotGraph Source

Convert a graph to dot format, using the specified clustering function to group nodes into clusters. You can then write this to a file and run the appropriate command on it (found using commandFor). Clusters can be nested to arbitrary depth.

graphToGraph :: forall gr a b. (Ord 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. Note that this doesn't support graphs with clusters.

readDotGraph :: Parser Char DotGraph Source

commandFor :: DotGraph -> String Source

The appropriate GraphViz command for the given graph.
