How to create a pie chart using the chart module in Drupal 7? I'm trying to create a pie chart using the chart module. I was able to create a pie chart that looks similar to the pie chart shown on https://developers.google.com/chart/ . But I am not getting any percentages.

My Question: What is needed to also show those percentages, or what might I be doing wrong)?

Note: I cannot do those interactive additions, but I can live without them.
Yes it is possible to do so. Use the google chart tools to achieve that. This module also integrates with the views module nicely.
