DOT has two ways to specify edge direction. An undirected graph is ``` graph foo a -- b ``` and a directed graph is ``` digraph foo a -> b ``` But what is the correct interpretation of ``` graph foo a -> b ``` or ``` digraph foo a -- b ``` Current impl treats graph vs digraph as graph-level default and `--` vs `->` as edge-level definition.
