title: How to iterate through GeoJson Feed for Google Map
body: <p>So, I have a GeoJson Feed that looks like this</p>
  
  <pre><code> {
    "type" : "FeatureCollection",
    "features" : [
      {
        "type" : "Feature",
        "geometry" : {
          "type" : "Point",
          "coordinates" : [
            -84.50926612,
            39.1423275
          ]
        },
        "properties" : {
          "name" : "&lt;a href=\"/Things-To-Do/Attractions/cincinnati-zoo-botanical-garden\"&gt;Cincinnati Zoo &amp;amp; Botanical Garden&lt;/a&gt;",
          "description" : ""
        }
      },
      {
        "type" : "Feature",
        "geometry" : {
          "type" : "Point",
          "coordinates" : [
            -84.495935481675,
            39.095853705988
          ]
        },
        "properties" : {
          "name" : "&lt;a href=\"/Things-To-Do/Attractions/bb-riverboats-thanksgiving-day-cruise\"&gt;BB Riverboats Thanksgiving Day Cruise&lt;/a&gt;",
          "description" : ""
        }
      }
    ]
  }
  </code></pre>
  
  <p>I am loading it with this function</p>
  
  <pre><code>var attbut = document.getElementById('loadatt');
  attbut.addEventListener('click', function() {
  var xhr = new XMLHttpRequest();
  xhr.open('GET', 'path-to-GeoJson', true);
  xhr.onload = function() {
  loadAttractions(this.responseText);
  };
  xhr.send();
  });
  </code></pre>
  
  <p>And it is loading fine.  However I can't seem to get the 'length' property to iterate. </p>
  
  <pre><code>function loadAttractions(results) {
  log(results.FeatureCollection.length);
  for (var i = 0; i &lt; results.FeatureCollection.length; i++) {
  var coords = results.features[i].geometry.coordinates;
  var latLng = new google.maps.LatLng(coords[1],coords[0]);
       var marker = new google.maps.Marker({
       position: latLng,
       map: map
       });
  }
  }     
  </code></pre>
  
  <p>I have tried <code>results.features.length</code>, and <code>results.FeatureCollection.features.length</code>, the only thing that "works" is <code>results.length</code>, which gives the whole array.  Everything else gives an undefined error. </p>
  
  <p>Thanks for any suggestions or help.  </p>
