Add box mark to auto

[tophtucker]

Plot.auto would never choose box by default, but you could override to it, thereby allowing box plots in the chart cell on Observable. See #1422

Still a decent idea, at least for box plots, but stale and trivial, so closing for now! More in the issue: #1422

Seems like a quick win if we want to add box charts to the chart cell. I’m supportive! (Voronoi seems more dubious.)

K, reviving! 🧟 Box only now. I wonder if we should try some approach for the quant-quant case like you describe in #1330 (comment). I wanna test a bit more… notebook demo: https://observablehq.com/d/5efa14f16d261488

More test cases in notebook now: https://observablehq.com/d/5efa14f16d261488

Breaks if color is anything but redundantly encoding categorical dimension:

Cat-cat shows nothing:

Quant-quant is tricky (see #1330):

Just checking in on my stale PRs…

• This should wait for box tip aggregate #1843
• This would benefit from The box mark could use bin/rect instead of group/bar for quantitative data #1330, but I don’t think that blocks it
