Pie chart does not support the 'tooltip' role. You can see which roles are supported by which chart in the Data Format section of the chart documentation. For example, see the Area Chart Data Format<http://code.google.com/apis/chart/interactive/docs/gallery/areachart.html#Data_Format>vs. the Pie Chart Data Format<http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Data_Format> .
