In the bokehjs repo, we have some unittests which demonstrate the capabilities - thus far we've focused mainly on getting things ready for demos, and we've SORELY neglected documentation, ease of getting others setup. But now that we have some downtime after PyCon, we'll be working on this very soon. So I guess what I'm saying is, wait a week, and those demos will be available. If you're really eager, you could clone the repo, but it's quite hard to get up and running right now.
