<h1>Marker Clustering</h1>
<p>Cluster multiple markers together to better visualize the data</p>
</div>
<p>This example displays a map showing the distribution of
airports across the world. The locations were obtained by using
the <a href="http://openflights.org/data.html" target="_blank">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>
<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.
The result is added to the map as an additional layer using the <code>map.addLayer()</code> method.</p>
