Is the animator graph editor exposed to the API? Unity 4.0

Is the animator state machine editor exposed to scripts in Unity 4.0? If it is, is there any documentation yet? If it isn't, will it be exposed in the future?

I ask because I would love to make custom graph editors for other things besides just animation and the built in animation graph editor seems like it could be a powerful and easy way to do that. Thank you for your answers!
