Google-style Pie Chart Labels
Sometimes the pie chart labels cannot be displayed, or are difficult to understand when the pie pieces are thin. Google's chart API (http://code.google.com/apis/chart/docs/gallery/pie_charts.html) places the labels outside of the chart with lines denoting pie pieces.
Implemented as of version 2.1
