Add the figure element to the context

[Fil]

Currently context contains the ownerSVGElement property (the chart's svg), but not the main element (figure or svg), making it a bit difficult e.g. to listen to the chart's own "input" events (and more…).

It would be useful here for example https://observablehq.com/@fil/ternary-plot#comment-5ba7a42661249bb9

Thanks for your reply. Too bad that title and caption are not supported yet.

I’m trying to use ternary plots like SenseMaker does: https://observablehq.com/@martien/making-sense-with-ternary-plots.

P.S. I’d also like more control of labels, e.g.

• auto wrap long labels;
• auto set text-anchor start or end, depending on apex position right or left from middle of sphere;
• a bit more space between label and apex;
