Google map to attach to. 39 * @param {Array.<google.maps.Marker>=} opt_markers Optional markers to add to 40 * the cluster. 41 * @param {Object=} opt_options support the following options: 42 * 'gridSize': (number) The grid size of a cluster in pixels. 43 * 'maxZoom': (number) The maximum zoom level that a marker can be part of a 44 * cluster. 45 * 'zoomOnClick': (boolean) Whether the default behaviour of clicking on a 46 * cluster is to zoom into it. 47 * 'averageCenter': (boolean) Whether the center of each cluster should be 48 * the average of all markers in the cluster. 49 * 'minimumClusterSize': (number) The minimum number of markers to be in a 50 * cluster before the markers are hidden and a count 51 * is shown. 52 * 'ignoreHiddenMarkers': (boolean) Whether to ignore markers that are not 53 * visible or count and cluster them anyway 54 * 'styles': (Array) An array of objects with these properties: 55 * 'url': (string) The image url. 56 * 'height': (number) The image height. 57 * 'width': (number) The image width. 58 * 'anchor': (Array) The anchor position of the label text. 59 * 'textColor': (string) The text color. 60 * 'textSize': (number) The text size. 61 * 'backgroundPosition': (string) The position of the backgound x, y. 62 * 'iconAnchor': (Array) The anchor position of the icon x, y. 63 * 'cssClass': (string) One or more CSS class for styling this marker. 64 * 'onMouseoverCluster': (function) The event handler used for onmouseover 65 * each cluster 66 * 'onMouseoutCluster': (function) The event handler used for onmouseout 67 * each cluster 68 * 'drawCluster': (function) Custom draw method for ClusterIcon 69 * 'hideCluster': (function) Custom hide method for ClusterIcon 70 * 'showCluster': (function) Custom hide method for ClusterIcon 71 * 'onAddCluster': (function) Custom onAdd method for ClusterIcon 72 * 'onRemoveCluster': (function) Custom onRemove method for ClusterIcon 73 * @constructor 74 * @extends google.maps.OverlayView 75 */
