Display statistical data on a region map

Hi all,

My rails 2.0.2 application needs to display the sales of my client
regionwise.
ex: Display colours in various states of a country scale wise.
I've already wasted 2 days behind this but still not got anything to
start with.
Can any one help please...

If it's the US, you can use gchart (http://gchart.rubyforge.org/
gchart/)

  g = GChart.map(:area => 'usa', :data => {'NY'=>1,'VA'=>3,'CA'=>2})
  g.to_url
