Could you define the term "dimensional charting" in your README?

I think it makes sense to provide a simple introduction for users who don't have experience with this type of thing.

Dimensional design is a data warehousing concept, grossly oversimplified it means your data must be organized into tables called facts and dimensions. "Dimensional" in dimensional charting means that your data must first be organized in that fashion.

To understand this in more detail, there are books about this field, like Data Warehouse Toolkit by Ralph Kimball for example.

I'll try to add a little bit more of an introduction for 2.0

Well, I'm adding a few words - not trying to provide a comprehensive definition of dimensional charting, but saying what dc.js does.
