        <h1>Marker Clustering with Custom Theme</h1>
        <p>Cluster multiple markers and customize the theme</p>
    </div>
    <p>This example displays a map showing geo-tagged clusters of photographs 
      taken from locations around the world. The <a href="http://commons.wikimedia.org/wiki/Main_Page" target="_blank">Wikimedia Commons</a>
      website was used to provide a source of data of geo-tagged images.</p>
    <div id="map"></div>
    <h3>Code</h3>
    <p>Marker clustering requires the presence of the <code>mapsjs-clustering</code> module of the API. The 
      <code>H.clustering.Provider</code> class is used to load in data points and prepare them for clustering. </p>
    <p>Customizing the default look-and-feel of the <code>clusters</code> and <code>noise</code> points is 
      very easy. When instantiating the <code>H.clustering.Provider</code>, a <code>theme</code> object holding two methods - 
      <code>getClusterPresentation()</code> and <code>getNoisePresentation()</code> - is passed as an additional parameter 
      into the constructor. Both <code>theme</code> methods must return an <code>H.map.Object</code> such as a marker or polygon etc. 
      More information can be found in the API Reference.</p>
