Google maps: place number in marker?

Question

How can I display a number in the marker on a google map? I want to do server side clustering and I need to display how many points the cluster represents.

Answer 1

icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=1|FE6256|000000'

Looks fine with 1-digit and 2-digit numbers
