GraphConfig Documentation would be nice

There's a number of not entirely self-evident variables in GraphConfig that could perhaps benefit from some documentation/explanation.

I can agree. Luckily the package is pretty solid as is so it isn't too hard to intuit, but even just some doc comments around the properties would be fantastic. I'm kinda just guessing at what exactly they're supposed to do and fiddling around until I get the graph I want.
