Feature request: Warn when declaring duplicate nodes
Filing this bug, not as high priority, but to track this piece of feedback I saw the other day.
I read https://swagitda.com/blog/posts/security-decision-trees-with-graphviz/ -- a great post about how to use Graphviz, and they say:
Also note that Graphviz does not warn you if there are duplicate nodes, so choose whichever organization option will minimize the probability of you creating duplicates.
I also found this question: https://stackoverflow.com/questions/32422592/force-graphviz-to-complain-for-duplicate-nodes
This seems like something we could potentially bake into the core of graphviz?
