title: How to set google map marker by latitude and longitude and provide information bubble
body: <p>The following sample code provided by google maps api</p>
  
  <pre><code>          var geocoder;
            var map;
            function initialize() {
              geocoder = new google.maps.Geocoder();
              var latlng = new google.maps.LatLng(40.77627, -73.910965);
              var myOptions = {
                zoom: 8,
                center: latlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP
              }
              map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
            }
  </code></pre>
  
  <p>the following only shows google map of the location without a marker. 
  I was wondering how I can place a marker by giving latitude/longitude parameters?
  And how is it possible to store my own information pulled from a database on that marker?</p>
