Another comment, at the risk of sounding like a crazy fanboy. After years of use, I still can't get enough of D3, it doesn't feel like JavaScript yet it fully embraces the best parts of the language.
It is indeed a lot more difficult to learn than other solutions, but with the experience it becomes second nature to "think in it" and explore data iteratively, building visualizations along the way all while having fun (and its concepts map very nicely with how Edward Tufte lays out things in his books).

All this to say: thank you.
