Not OP, but a someone who uses D3 every day, it gives you (almost) total freedom. You can decide where to put your x and y axes, legends, labels, etc. You can decide how data determines not just how something appears on the screen (like a bar chart of y height) but how the underlying data determines its classes and styling, etc.
D3 is awe-inspiring in its scope, and learning to use it has a steep learning curve. But for anything beyond trivial use cases the freedom it affords you is worth the effort.
