In this example, a very simple pie chart is created demonstrating the basic steps in creating pie charts.

• Create a pie chart object using PieChart.PieChart.
  
  
• Specify the center and radius of the pie using PieChart.setPieSize.
  
  
• Specify the data used to draw the pie using PieChart.setData.
  
  
• Generate the chart using BaseChart.makeChart2.
