Hey potkea! Id potentially make the data into fewer cuts, which would eliminate the number of shades & simplify this overall…maybe 250/500/750/+.

What you’re really drawing attention to is outliers, and they’ll remain as such even with fewer cuts. You can also put the “incidents per 100K” somewhere ONCE - no need for it written out each time. With newfound space (or maybe even without), blow the map up larger, and maybe add a few labels somehow, calling out major cities (small, potentially unnecessary idea tbh), but could be helpful to orient.
