How to display two or more markers on the same location?

An answer to this question on Stack Overflow.

Question

I have a question about the GOOGLE MAP API. If you have more than two data that share similar address, how do you show the Pins Drop on the same address?

Example

  1. You have data such as the following:

     Name=>Ray | Address=>Melon Park, California, USA ; 
 Name=>John | Address=>Melon Park, California, USA ; 
 Name=>Steve | Address=>Melon Park, California, USA

  2. You want to display 3 Pins Drop for the similar address on Google Map.

Answer

I achieved this using a "spiderfier" to "spiderfy".

There is a GoogleMaps v3 Spidifier available here (demo).

Leaflet.js can also load GoogleMaps v3 and has a beautiful clustering spidifier available here (demo).
