In figure 2( a) the compound score for evaluation comments of external USD DVDCD as the 3D surface versus the variety of positive and unfavorable words is revealed. This 3D surface reveals the variation in the compound rating for a particular product due to the variety of negative and positive words.

In figure 3, the 3D column chart is depicted for external USB DVDCD and GE 72887 Superadio III Portable AMFM Radio. The substance rating for the evaluations is plotted as column chart against the number of favorable words along the x-axis and variety of negative words along the y-axis. Utilizing this 3D column chart the qualities of product reviews can be understood.
