title: Create clickable element in Google Visualization line chart
body: <p>Is it possible to attach an onclick method to the elements within a Google Visualization line chart? For example, if a user clicks on point within the chart I want to send the user to a page with more details. I've gone all through the documentation and can't find an example of how to do this. </p>
  
  <p>I see that there are methods for events (from the <a href="http://code.google.com/apis/chart/interactive/docs/gallery/linechart.html" rel="nofollow">documentation</a>) but with no clear example it's not making much sense.</p>
  
  <p>Thanks!</p>
