I think the reason dc.js works so well is that it is tightly coupled to crossfilter (http://square.github.io/crossfilter/). This manages the multi-dimensional views that dc.js leverages to render charts.

When developing, the chart bit is usually the easiest bit to implement. Getting the data set into the views you need is where you spend a lot of time.

Good luck with the chart engine!
