I have a graphviz file automatically generated, which sometimes produces double connections, e.g.
"test textanalysis" -> "development" [color="white"];
"development" -> "test textanalysis" [color="white"];
I'd like to know
1) if it is possible to show this as a single connection with double arrows at start&end in Graphviz
2) or in alternative if you know a Python way to filter out one of those lines (I dont mind losing that information): I cannot find a regex able to do it!
