Interactive legend to mimic PlotlyJS.jl

[alex180500]

Hi, in Plots.jl using PlotlyJS backend I can plot multiple plots at the same time and get a legend where I can click the legend names to hide/show a line or a scatter.

Is it possible to achieve a similar result in GLMakie?

There have been attempts to get something like this going, check the issues or PRs, there were definitely some proof of concept implementations. I think it didn't go anywhere so far because doing this by default adds another layer of observable connections that we were not super keen to have by default I think, and such a functionality seems to have a lot of edge cases (for example, what happens with the legend when you delete!(ax, someplot), should a plot know about legends it's represented in to notify them of deletion?)

I think maybe some hide parameters that is notified by the clicks in the legend.
