What is the graph = None arg?

[qzmfranklin]

What is the point of using a class if you pass in the graph as a parameter anyways?

It's a flexibility thing. Without the optional graph arg, you perform stateful operations on the object. If you pass graph in manually, you can use the methods as if they're static methods.

Just saw you closed the issue.

Then just make it a staticmethod, then call the static method from the class method. Otherwise people cannot figure out the intention without actually understanding the source code. This is just defeating the point of using an API

Thanks for your input. This is a tiny library I built for myself; I'm happy other people somehow found it and are using it but I'm not going to contribute any direct maintenance unless it's something I personally need. And I, personally, can use it fine the way it is.

I encourage you to either submit a PR with your changes for review or fork the library. This library is available under the MIT License so you can do basically whatever you want with it. If you make a version significantly better than this one I will probably move over to using yours.

I've added a small note to the README to reflect this 84d4835
