Ah right. Yeah that’s what I was aiming for, I just did it via @radius instead, as it was on my mind at the time. But the original idea there was for it to tell you what single point you’re hovering over.
A more useful, though larger, change would be to have more values being returned as a list, but that starts to become a bit more a standalone patch or example.
A change like being able to have symbolic labels would also make for a handy pre-processing abstraction where you can start with a larger dataset and then visualize up to 3 arbitrary dimension from it, ala @tedmoore’s plotter.
