conda installs both graphviz and pygraphviz while pip tries to find graphviz on your computer and install pygraphviz to link to it. At least that is my probably poor attempt...

It looks like the return type of `agattr_label` has been corrected to `Agsym_t *`. The impact of setting the type of the parameters mentioned above to IDTYPE is not clear...

This [StackOverflow question](https://stackoverflow.com/questions/42463616/how-do-i-order-subgraph-clusters-when-using-dot) suggests that the order of subgraphs can be tricky even when creating the dot file from scratch. Pygraphviz handles it however the GraphViz `cgraph` library handles it,...

pygraphviz can only do what GraphVIz can do. I haven't heard of such a feature from Graphviz. But I haven't ever looked for it.

[NetworkX has JSON ](https://networkx.org/documentation/stable/reference/readwrite/json_graph.html)as one of the input/output formats. It also connects to the pygraphviz package.

I'm afraid this is beyond my expertise. Not even sure how to test it to see if it works on my machine. Any hints on good ways to check if...

PyPy fails during setup because it can't find a ```python_library``` (python_library is None [here](https://github.com/scikit-build/scikit-build/blob/master/skbuild/cmaker.py#L202). And there is a TODO comment about it [here](https://github.com/scikit-build/scikit-build/blob/master/skbuild/cmaker.py#L422)). I don't know enough about skbuild or...
