Title
Body
Here is a very simplified example of my Dot graph: strict digraph graphName { A->B B->A } This creates Instead I want a single edge shown between A and B but with a double arrow head. I know how to get the double arrowhead as a global option: strict digraph graphName { edge [dir="both"] A->B B->A } But that looks very ugly, and not all of my edges should be dual headed. If I do more processing of the graph and detect the double reference myself and replace the two edges with a single edge, it looks OK. But I'd rather not have to do this extra step strict digraph graphName { A->B [dir="both"] } Any better solutions?
