graphic chart

Question

I have a requirement to drill down the heat map chart.

I need a framework javascript. I checked extjs , highcharts . But until now, not anything attractive.

I want exactly the same way as Google Analytics. First map of the world

Once I click on the United States, I bored to the state level

Do we have a google api? Any structure?
