Recently I made a few base maps of various-sized buffers around ad hoc points. This type of request is quite common from my colleagues - draw a circle around a given point to understand relationships of distance.
I thought to myself - there must be a tool which allows one to drop a point on a map and see arbitrary distances, and to simply visualize these.
