Someone asked me to post this here - so that he can give it a try!
I did a Lightning Talk at CiviCON 2016 showing how you can put your Contacts on a Leaflet Map. It only takes a few minutes to put your CiviCRM Contacts on a Leaflet Map if you're using Drupal. Leaftlet is an open-source JavaScript Library for interactive maps. In addition what's really cool is that you can color the PIN based on the value of a CiviCRM custom field!
I've posted the details in a QA format including some of my slides from my CiviCON Lightning Talk on CiviCRM's StackExchange site:
