Optionally clip marks to the canvas area?

[mbostock]

And related, you might want overflow: visible on the SVG element?

We can already add style: { overflow: "visible" } as a top-level property.

We can imagine two use cases:

1. hiding the values that exceed the domain's bounds
2. putting them a few pixels to the left of the min (resp. right of the max); maybe linked to the unknown/others properties (see Can't set unknown domain in colour scale #446)

Any idea for a syntax?

Here I could see us supporting a clip: true option for the x and y scales. But in some cases I could see us wanting to control the clipping on a per-mark basis. I’d rather implementing the clipping functionality centrally, though; I don’t want each Mark to have to implement it on its own.
