Control axis z-order?

[mbostock]

E.g., below the hexbins are drawn on top of the axis, but I’d rather the axis be drawn on top

Generally we'd want to draw areas below the axes, and lines and points above them, so in a sense it feels we'll need more than a binary choice (of top vs bottom).

What if we could control the z-order of each mark individually (with a default of 1), and axes would be set to 0?

There are also some cases where you might want to interleave instances of marks, but that’s probably overkill for now.
