title: Google Maps API and GeoJSON: How do I create different colored lines with unique properties and infowindows
body: <p>I am having a problem with GeoJSON and Google Maps API. <br/>
    How do I plot a MultiLineString with ... <br/>
     1) Each line having It's own color and <br/>
     2) Each line having it's own properties and<br/>
     3) Each line should be clickable and show an info window with it's properties <br/>
  <br/>
  Samples Javascript:<br/></p>
  
  
  
  <pre class="lang-js prettyprint-override"><code>var dataGEOJSON=[];
  function LoadMyGEOJSON(key)
  {
      dataGEOJSON[key] = new google.maps.Data();
      dataGEOJSON[key].loadGeoJson('GetLatLngGEOJSON.aspx?key=' + key);
      dataGEOJSON[key].setMap(map);
  }
  </code></pre>
  
  <p>The reason for the array, is that way I can keep track of the keys they loaded, as the user can load or unload the keys from the map in their user interface.<br>
  <br>

  <p>This is the first time I am using GeoJSON, so I will need assistance with the GeoJSON format needed for to add the properties and styles.  Plus the javascript and Google Map API code.
  If anyone can provide some code or a link to some resources which give detailed examples, that would be greatly appreciated.</p>
