Answer 1

I little birdie told me that you can find a .pdf of the JFreeChart documentation on a popular BitTorrent tracker.

Answer 2

It's possible though it won't look exactly the same. The easiest way is to create a dataset (descendant of org.jfree.data.general.PieDataset) and use one of org.jfree.chart.ChartFactory methods:

PieDataset data = new DefaultPieDataset();
data.setValue("Section1", 30);
data.setValue("Section2", 60);
data.setValue("Section3", 120);
JFreeChart pieChart = ChartFactory.createPieChart3D(
 "My Pie Chart", // title
 data,           // data set
 true,           // draw a legend
 true,           // show tooltips over sections
 false);         // do not generate image map with URLs

You can then further customize your chart through pieChart methods. For example, here's how to explode one pie section:

 PiePlot plot = (PiePlot) pieChart.getPlot();
 plot.setExplodePercent("Section2", 0.25);
