This is one of the planned items, as you can see in the map:
- Show 161 m / 0.1 mi circles
It is not possible in Live map yet, but you can do that in all the other map tools. For example in Map Compare. You can select only single user, show all caches. In the map then hover on the geocaching icon (circle with cross) and click on the most right icon with circle.
It will draw the circles around all the caches on the map (including the caches with corrected coordinates and so on).
