title: Multiple markers - Same coordinates
body: <p>I'm having some troubles trying to display 2 different markers placed at exactly the same coordinates.</p>
  
  <p>The case is: we are displaying stores, and some of them are placed at the same building (ie. a mall), so, they are different stores but shares the same ubication/coordinates.</p>
  
  <p>Our json source content looks like this:</p>
  
  <pre><code>  {
       "properties" : {
          "id" : "1",
          "name" : "Store 1"
       },
       "geometry" : {
          "coordinates" : [-70.66667, -33.45],
          "type" : "Point"
       }
    },
    {
       "properties" : {
          "id" : "2",
          "name" : "Store 2"
       },
       "geometry" : {
          "coordinates" : [-70.66667, -33.45],
          "type" : "Point"
       }
    }
  </code></pre>
  
  <p>The thing is, just one of them gets displayed.</p>
  
  <p>My question is, is there an out of the box solution for this use-case? Or should we implement our own solution ?</p>
  
  <p>Thanks in advance!</p>
