Reduce the size of circles when the size of the global figure is diminished.

[ZheFrench]

I'm trying to reduce the diameters of the circles.
When I reduce the size of my figure , at some point circles overlaps and it's not clean.
I would like to remove the overlap between black/grey circles.
This what I produced for now here.

Did you try changing size for geom_point as in this example: https://krassowski.github.io/complex-upset/articles/Examples_R.html#adjusting-the-intersection-matrix ?

Nope, but this is a good advice ! I'll give a try.
I end up with height_ratio=1, who did the job.
Tks.
