This is due to the [HTML-style labels feature](https://graphviz.org/doc/info/shapes.html#html) being used in your example. The Graphviz docs say that the label is either a string delimited as "..." or an HTML...

The graphviz build must not include support for png files. In part of your log, our docstring talks about that and those words come from the Graphviz docs. The docstring...

That would be nice. Do you happen to know a reasonable way to check if that support is available? Otherwise we'll look for it... Thanks!

Check out [the documentation](http://pygraphviz.github.io/documentation/pygraphviz-1.4rc1/) (or the source code). It looks like you will need to flatten your nested-dict data structure so that ```test_dict[n]``` iterates across the neighbors of ```n```. Does...

Your examples don't describe the format you are using sufficiently. Is this a standard somewhere? It seems like flattening your example WOULD work... Why wouldn't ```{node1: [node1_1], node_1_1: [node1_2], etc...

I think you misunderstand the example. The examples show an "adjacency" data structure. It is a dict keyed by node with values being a dict keyed by neighbor with values...

Thanks for this -- it looks like it also doesn't carry forward the `name` attribute. This is similar to #354 with fix #356. ```python G = self.__class__(strict=self.strict, directed=self.directed, name=self.name) ```

In this case `self.__class__` is the class `D`. It is not the inherited `__init__` that is called. It is the subclassed `__init__` you are writing. And that has no input...

Your subclass can add extra input arguments, but not remove arguments needed for the base class. You should include a keyword argument in your subclass for "strict" and then handle...

You should use the conda-forge collection of conda packages. ```conda install -c conda-forge pygraphviz```
