Drill down charts using

[John]

Dear friends,

I want to use the Google Chart API to create drill down bar charts.

For example : I want few European countries( UK,Germany, Italy,
Greece) to be displayed on the first bar chart. When i click on
Germany, I want another bar chart displaying Germany cities like
Frankfurt, Berlin, Bonn etc to be displayed.

I see few configuration event options here :

http://code.google.com/apis/chart/interactive/docs/gallery/barchart.html#Events

Can somebody help me in configuring the event "select" /
"onmouseover" ? I would be very grateful if you do.

Thanking you,

Regards,
John

Note - I do not want Flash charts, I am interested on HTML5 &
javascript charts.
