I am using the MarkerCluster.js to create clustering in my google maps api. The clusters work how I want them however I want to style differently than yellow, blue and red circl
It's never too late to post a rather helpful answer, so additionally you can look through the whole MarkerClusterer Documentation for IconStyle
UPDATE
There's also google maps v3 utility on github as stated by ehcanadian
What you need to do is use the url to specify which images to use instead of the blue/yellow/red images currently being used. And probably a good idea to include the height and width options too.
var clusterStyles = [
{
textColor: 'white',
url: 'path/to/smallclusterimage.png',
height: 50,
width: 50
},
{
textColor: 'white',
url: 'path/to/mediumclusterimage.png',
height: 50,
width: 50
},
{
textColor: 'white',
url: 'path/to/largeclusterimage.png',
height: 50,
width: 50
}
];
