Pie Chart, represented in the circular chart symbol, is easy to understand complex data. Each section of the circle shows the data value proportions. The Pie charts can be of two-dimensional view or three-dimensional views based upon the taste of the user. In this example, I am going to use R package plotrix to draw a 3D pie chart.

Prerequisite

We need the following R libraries to run the script
