Hi,
For those who would take times to read my answer, it could be cool if you can give me your advise on issue #68 (
https://github.com/glejeune/Ruby-Graphviz/issues/68). Briefly, the problem is about the fact the order in which the "elements" given to create the graph is kept. So the question is, must we find a solution to solve issue #68, and if yes, how ?
