I have verified that this works on other systems -- indeed it is verbatim in the doctest for ```AGraph.add_edge```. So it has been tested regularly. This is a very strange...

I was able to reconstruct your output! (using GraphViz 2.40.1 and python 2.7 instead of GraphViz 2.38.0 with python3.6) Python 3.6 should not be a problem. Python 3.7 runs into...

Yes -- there's a bug that is fixed in 2.42 whenever that gets released. We'll shift to that when its ready. But meanwhile only 2.38 works.

Should be fixed when version 2.42 comes out. But that doesn't seem to be a quick process. Thanks for confirming that switching to v2.38 works.

I think the best solution for this issue is to update the doc_string at https://github.com/pygraphviz/pygraphviz/blob/1817fdfff453ffa509380b1452dc736d569a9f03/pygraphviz/agraph.py#L1536 to include a sentence saying the StringIO objects should only be used while explicitly setting...

I can verify/reproduce this problem. It seems like the file is not being closed and then the extra character is being read when the next file is opened. Very strange...

Thanks for working on this. Pygraphviz is a wrapper around the ```cgraph``` library from GraphViz. I don't think it needs the entire GraphViz program bundled with it. But I'm not...

(Linux build) The tests you point to are failing in many places, but the failures are all coming from an extra space added: ```graph {``` instead of ```graph {```. I...

I was mistaken earlier when I said the only libraries/files needed were ``libcgraph``` and ```cgraph.h```. We also need ```libcdt```.

OK... first thing I notice: GraphViz v2.40 has a known bug for multigraphs that has been fixed in the latest unreleased version of Graphviz. That fix will be available in...
