It's sort of a follow-up book, Paco.

I fully agree with Gavin. You're looking at two different people here — even if you do find a person who fits most of those requirements, it would certainly be too much to handle and the outcome won't likely meet your expectations. I'd look for a UI or visual designer with experience in mobile (to tackle the last couple requirements) and a user experience designer to support that first role (and tackle the first couple requirements.)

I have to say I find D3 (as well as its predecessor Protovis) a little hard to digest. I'm not sure if it's because of its approach or syntax, but I always had troubles figuring out how to chart my data with it. I do understand it does pretty cool stuff, though.

On the other side, Snap.svg seems to be quite designer-friendly. The syntax Dmitry (which by the way is the guy behind Raphael) is using is a plus: it's closer to jQuery, thus making charting slightly easier for the average designer. I can only speak for myself, of course.
