Hello I am trying to figure out how to create concentration of ID's in the
following data, based on determining the highest concentration in the smallest
radius area based on Longitude and Latitude (geo location)
I have reviewed many websites looking for a function or tutorial, (if you are
aware of either please let me know)
I have worked through the following to see if they are close to what I need, but
they are not.

My actual data is 2353 records with 41 states and 1337 cities represented. Here
is a sample below.
Some might call this a hotspot question I suppose: "What is the maximum
number of ID's I can gather in the smallest radius size given the data at
hand?
For example it would be useful to have a function that I could use to test
different combinations of radius size and concentration of ID #'s by geo
location.
Any insight would be very much appreciated.
Thank you.
