HighCharts has a really nice drilldown feature: http://www.highcharts.com/demo/column-drilldown - but I'm wondering if it's available in google charts visualization API? So far as I can tell, it's not possible - but let me describe my idea:
On mouseover, a small pop-out window with additional information about the data is available. Is it possible to place a link in that?
Because we have these mouseover events on the chart, perhaps it's possible to add a "click" event where we can do whatever we want with it? In this case, I'd either just have a click send the user to another URL, or possibly force the chart into a new chart animation (basically creating the drill down in this manor).
I'm not too great with jQuery, so I'd appreciate some expertise here. Thanks!
