title: Google maps marker title not showing up?
body: <p>I've added a map with a marker to my website but I'm not sure what the Title attribute does for the marker.</p>
  
  <p>I've used the documentation from the developers.google website</p>

  <p>In this example what does the "hello world" (marker title) exactly do?
  I am on OS X El Capitan - Chrome</p>
  
  <pre><code>function initMap() {
    var myLatLng = {lat: -25.363, lng: 131.044};
  
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 4,
      center: myLatLng
    });
  
    var marker = new google.maps.Marker({
      position: myLatLng,
      map: map,
      title: 'Hello World!'
    });
  }
  </code></pre>
