There is some way to set custom class in <circle> tag in my scatter plot??

I have 2 scatter plot and i wanna connect the point of each plot.

I do not know if this is the best or the right way but i wanna set a custom class to my dots, so in that way i can click in dot in plot A and and change color in the dot with the same class on plot B.

I’m using Angular framework with:

import * as Plot from “@observablehq/plot”;

No (but see className option for marks · Issue #1002 · observablehq/plot · GitHub). However you can select the marks by their aria-label.
