Proposal: Axial Swarm Plot

[alexlenail]

Seaborn's swarm plots tend to be a little slow, limiting the size of the plot. It would be lovely for Axial to provide fast, large-scale, interactive swarm plots. There's an opportunity here for some sexy animations in here too.

Since this would be an entirely new visualization, it might be a good place to break ground on a Vega-based Axial plot. Vega has swarm plots. How performant are they? I see they're rendered to the canvas, which is promising.

Alternately, Axial could try something more dramatic for swarm plots -- how could this classic visualization be improved? Could it be animated? Could we do something better than dots? Could it add more information than just being pointilliste violin plot?
