Please do not use github.io as a CDN unless you need the bleeding-edge features, as it is not stable (and GitHub doesn't like you doing that). In particular, we are sorry to report that nickqizhu.github.io/dc.js/* went away when we transferred the project to dc-js.github.io.

If you really must use github.io as a CDN, the URLs are:
