This example demonstrates various options in the "circular label layout" method. It also demonstrates the use of alternative sector label format.
By default, in "circular label layout", the sector labels will be external and close to the perimeter of the pie.
The PieChart.setLabelPos method can be used to control the distance between the sector labels and the perimeter. It also allows enabling join lines to connect the labels to the sectors, which are useful if the labels are far away from the perimeter.
The distance between the sector labels and the perimeter can be negative, in which case the sectors will be internal to the pie.
Note also the sector label format in this example, which consists of 3 lines. It is specified using PieChart.setLabelFormat.
