I'm not familiar with all the available chart libraries built on top of d3.js，but having used vanilla d3 on several projects, my first response to this article was that c3 looks really useful/cool... That said, it's probably worth mentionting that there are some useful examples of "reusable charts" on mr. bostock's website, and constructing a customized version of this JSON chart format probably wouldn't be too difficult, although making it performant on large datasets might be.
