title: Find frequently visited area from given set of GPS points
body: <p>I am having a data set of say 10000 GPS points. I need to find GPS points depending on how frequently the area is visited by using the GPS data set I have. I am looking for a solution either by using google maps or by using mongoDB, but unable to find any clue how should I achieve this. Can anyone help me regarding this?</p>
  
  <p>sample data =  <code>[{18.5204303,73.8567437},{18.520457, 73.856697},{18.520400, 73.856800},{18.520156, 73.857092},{18.519879, 73.857561}]</code></p>
  
  <p>Out of the given data set first three point are near to each other.
  So, whenever I will ask for frequently visited area from the given data set I should get result as <code>[{18.5204303,73.8567437},{18.520457, 73.856697},{18.520400, 73.856800},{18.520156, 73.857092}]</code></p>
