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.
