Where is the Google Marker Cluster?
<p>After adjusting to the new movements from Google to Git, one issue still persists.</p>

<p>What shall I do get the marker cluster rendered on the map, instead of a <code>?</code> ?</p>

<p>I am using a coffee script:</p>

<pre><code>class RichMarkerBuilder extends Gmaps.Google.Builders.Marker #inherit from builtin builder
  #override create_marker method
  create_marker: -&gt;
    options = _.extend @marker_options(), @rich_marker_options()
    @serviceObject = new RichMarker options #assign marker to @serviceObject

  rich_marker_options: -&gt;
    marker = document.createElement("div")
    marker.setAttribute 'class', 'marker_container'
    marker.innerHTML = @args.title
    _.extend(@marker_options(), { content: marker })

  infobox: (boxText)-&gt;
    content: boxText
    pixelOffset: new google.maps.Size(-140, 0)
    boxStyle:
      width: "300px"

  # override method
  create_infowindow: -&gt;
    return null unless _.isString @args.infowindow
    boxText = document.createElement("div")
    boxText.setAttribute("class", 'marker_info_box') #to customize
    boxText.innerHTML = @args.infowindow
    @infowindow = new InfoBox(@infobox(boxText))

@buildMap = (markers)-&gt;
    handler = Gmaps.build 'Google', { builders: { Marker: RichMarkerBuilder} } #dependency injection

    #then standard use
    handler.buildMap { provider: {}, internal: {id: 'map'} }, -&gt;
      markers = handler.addMarkers(markers)
      handler.bounds.extendWith(markers)
      handler.fitMapToBounds()
</code></pre>
