I certainly hope not!!!

(1) ``Given their low data density and failure to order numbers
along a visual dimension, pie charts should never be used.''
(Tuffte, Edward R., ``The Visual Display of Quantitative
Information'' Graphics Press, Chessire CT, 1983, p. 178.)

(2)  ``3D pie charts are even worse, as they also add a visual
distortion ...''  (``How to Construct Bad Charts and Graphs'',
Klass, Gary, Department of Politics and Government, Illinois
State University, 2001.)
