tangent circle legend for size legend #14

There is an old suggestion in the ggplot2 ecosystem to procide with a more compact legend for bublble charts: For instance, from this stack overflow post :

Text labels could be inside the circle or offset outside with a small segment linking them to the circles.

I think your approach could make that really easy. I have tried to understand the code for guide_colour_ring in ggduidance. Looks feasible, but I am affraid it is beyond my reach.

I like this idea, but this is probably for a more distant future
