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...

Auto-detecting when this situation happens is more difficult than it seems at first glance. And it could be argued it's a type of scale (type="integer"), rather than a type of...

A [Voronoi mark](https://observablehq.com/@fil/plot-voronoi-0-1) could allow this, but more generally I'm wondering if we should have an event-based system for hover. `viewof plot` will be dedicated to the selection (or full...

My remark was more about separating the two signals: if the viewof channel is dedicated to filtering (typically brushing), I don't think it should be used to send information about...

Also need to mention https://observablehq.com/@fil/experimental-plot-tooltip-01 which partly addresses this issue. Again it shows some problems with (the way I intercept) the creation of a faceted *g* to add interactive behaviors....

I have fixed the links; if you play with them, I would be happy to have feedback.

I can't give a specific date but interaction is definitely on the roadmap.
