title: Stuck mapping location heatmap on python
body: <p>I am working on an exercise which consists on retrieving data from foursquare in order to determine where to add a Gym based on less competition.
  I have already called the API and cleaned my data, and was even able to map all the gyms.
  I am stuck, however in figuring out a way to use the data (coordinates) from my set, with the restriction that it needs to be limited to a specific area (I figured I can do top-left, right bottom coordinates for this).
  Any ideas?</p>

  <p>A solution using heat maps instead of an exact location would work as well.</p>
