title: GeoXML3 - Open an info window automatically
body: <p>I have created a polygon and would like the info window to open automatically on load. How do I do this?</p>
  
  <p>This is what I have so far:</p>
  
  <pre><code>var geoxml = null;
  
  function initialize() {
  
    infoWindow = new google.maps.InfoWindow();
    var myLatlng = new google.maps.LatLng(100.9530044, 110.8574693);
    var myOptions = {
      maxZoom: 13, 
      center: myLatlng,
      streetViewControl: false,
      zoomControlOptions: {
        style: google.maps.ZoomControlStyle.SMALL
        },    
        mapTypeId: google.maps.MapTypeId.ROADMAP,
      };
  
      map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
      geoXml = new geoXML3.parser({
        map: map,
        singleInfoWindow: true,
        infoWindowOptions: {maxWidth:350,cornerRadius: 12},
      });
  
      geoXml.parse('file.xml');
  
  };
  </code></pre>
