<p>This page's <code>map</code> element has its <code>tabindex</code> attribute set to <code>"0"</code>, that makes it focusable. To focus the map element you can either navigate to it using the "tab" key or use the skip link. When the <code>map</code> element is focused the + and - keys can be used to zoom in and out and the arrow keys can be used to pan.</p>
<p>When clicked the "Zoom in" and "Zoom out" buttons below the map zoom the map in and out, respectively. You can navigate to the buttons using the "tab" key, and press the "enter" key to trigger the zooming action.</p>

<h4 id="title">Earthquake Clusters</h4>
<p id="shortdesc">Demonstrates the use of style geometries to render source features of a cluster.</p>
<div id="docs">
<p>
This example parses a KML file and renders the features as clusters on a vector layer. The styling in this example is quite involved. Single earthquake locations (rendered as stars) have a size relative to their magnitude. Clusters have an opacity relative to the number of features in the cluster, and a size that represents the extent of the features that make up the cluster. When clicking or hovering on a cluster, the individual features that make up the cluster will be shown.
</p>
<p>To achieve this, we make heavy use of style functions and <code>ol.style.Style#geometry</code>. See the <a href="earthquake-clusters.js" target="_blank">earthquake-clusters.js source</a> to see how this is done.</p>
