title: Google Charts - is content drill-down in a chart possible?
body: <p>HighCharts has a really nice drilldown feature: <a href="http://www.highcharts.com/demo/column-drilldown" rel="nofollow">http://www.highcharts.com/demo/column-drilldown</a> - 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:</p>
  
  <p>On mouseover, a small pop-out window with additional information about the data is available.  Is it possible to place a link in that?</p>
  
  <p>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).</p>
  
  <p>I'm not too great with jQuery, so I'd appreciate some expertise here.  Thanks!</p>
