MarkerClusterer v3 Examples</h1>
<p>To use a marker clusterer, create a <code>MarkerClusterer</code> object.
In the simplest case, just pass a map to it.</p>
<pre class="prettyprint">
var center = new google.maps.LatLng(37.4419, -122.1419);
var options = {
'zoom': 13,
'center': center,
'mapTypeId': google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
var mc = new MarkerClusterer(map);
</pre>
<p>You may also specify a number of options to fine-tune the marker
manager's performance. These options are passed via a object.
</p>
<pre class="prettyprint">
var center = new google.maps.LatLng(37.4419, -122.1419);
var options = {
'zoom': 13,
'center': center,
'mapTypeId': google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
var mcOptions = {gridSize: 50, maxZoom: 15};
var mc = new MarkerClusterer(map, [], mcOptions);
</pre>
<p>Once you create a marker cluster, you will want to add markers to it.
<code>MarkerClusterer</code> supports adding markers using the
<code>addMarker()</code> and <code>addMarkers()</code>method or by
providing a array of markers to the constructor:</p>
<pre class="prettyprint">
var center = new google.maps.LatLng(37.4419, -122.1419);
var options = {
'zoom': 13,
'center': center,
'mapTypeId': google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
var mcOptions = {gridSize: 50, maxZoom: 15};
var markers = [...]; // Create the markers you want to add and collect them into a array.
var mc = new MarkerClusterer(map, markers, mcOptions);
</pre>
<h2><a name="Marker_Clusterer" id="Marker_Clusterer"></a>A Simple MarkerClusterer Example:</h2>
<p>This example will show 100 markers on map.</p>
<pre class="prettyprint">
var center = new google.maps.LatLng(37.4419, -122.1419);
var options = {
'zoom': 13,
'center': center,
'mapTypeId': google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
var markers = [];
for (var i = 0; i < 100; i++) {
var latLng = new google.maps.LatLng(data.photos[i].latitude,
data.photos[i].longitude);
var marker = new google.maps.Marker({'position': latLng});
markers.push(marker);
}
var markerCluster = new MarkerClusterer(map, markers);

<p>This example will compare adding markers with
<code>MarkerClusterer</code> to the normal method of adding markers, and
display the time for each.</p>
