I'm hoping that Raphael will get higher level API. I think g.Raphael went in that direction but more needs to be done.

Regarding Raphael, I think g.Raphael is a pretty high level interface for creating charts. It's find of on the level of protovis, which was what Mike Bostock was working on before he started d3, basically a declarative approach to chart generation. With d3, he went much lower level. And while this approach offers much greater flexibility, the learning curve is quite steep. It's not a framework you can pick up in a day or two unless you're already quite comfortable with Javascript, SVG, and the DOM.
