     <h1>Marker Clustering</h1>
     <p>This example displays a map showing the distribution of airports across the world. The locations were obtained by using the <a target="_blank" rel="nofollow" href="http://openflights.org/data.html">OpenFlights Airport Database</a>. Instead of adding a marker for each location, the data has been clustered, and individual airports are only shown at higher zoom levels.</p>
