title: Interface for viewing demographic information in maps
body: <p>I am involved in a research project where we try to find correlation between demographics and restaurant types.  We want to have an interface where we can apply the demographic information over a map of the city as filters and check how the restaurant types and information changes.</p>
  
  <p>I am lost on what sort of tools to use for this purpose.</p>
  
  <p>Note: I am not sure whether this is the right place to post this question.  If there is a specific SO site for this, I will move it there.</p>
