Nice work! I've been working on something very similar. My project still needs a lot of work (and talent, I started working on this site when I first learned html/css/js 2 years ago) but you can check it out at: http://subjectflow.com , or for a full tree: http://www.subjectflow.com/viewer.htm?=mewvzl2i6bt97gnjf9i4 (click on the white dots to expand the tree).
I really hope to see this type of idea take off. I would love to see this sort of thing combined with simplified git related operations to make it easy to improve education content. Additionally I think it would be great to add in a comment system where you can leave a question connected to the exact text that is confusing you.
