I'm trying to figure out how many points are within a pre-determined cluster size. For instance, I can create this map
I can see there are a few clusters and I can create a heatmap to illustrate the density. However, I'm trying to figure out how to set a cluster with a radius of 5, 10, and 20 miles and count how many points are within those cluster.
Do you know how to implement this in QGIS?
