VisX starts with low-level primitive components that match very closely to D3 primitives. It then builds some chart primitives on top of those and then builds some charts on top of that. You can build pretty much anything using the lowest-level primitives and still have a better developer experience than D3 IMO.

If you don't need any real customizability (and know you won't need it in the future), I'd stick with something with something less customizable, but faster to setup. If you know you need custom, take the 10-20% more time to setup and be able to change in the future as that'll be faster than porting your charts over.
