==============

A Google Maps JavaScript API v3 library to create and manage per-zoom-level clusters for large amounts of markers.
![Analytics](https://maps-ga-beacon.appspot.com/UA-12846745-20/js-marker-clusterer/readme?pixel)

[Reference documentation](https://googlemaps.github.io/js-marker-clusterer/docs/reference.html)

Migrated from the [Google Maps JavaScript API utility libraries on Google Code](https://code.google.com/p/google-maps-utility-library-v3/).

## Usage

Download or clone `markerclusterer.js` and images `m1.png` to `m5.png`, save images in `images` folder.

To use your own custom cluster images just name your images `m[1-5].png` or set the `imagePath` option to the location and name of your images like this: `imagePath: 'customImages/cat'` for images `cat1.png` to `cat5.png`.
