UMAP - Change marker size with zoom level

Hi there,

I'm wondering if anyone knows a way to change the marker size when zooming in and out? I am creating a map with almost 300 markers but when zooming out the markers are too large and overlap each other. If there was a way to make them smaller when zooming out it would look so much better.

There is an option for markers called "Zoom level for automatic zooms" but when I change the values nothing seems to happen. I'm not sure this option is even for what I think it is.

If anyone can help it would be greatly appreciated!

Thanks, Ross
