How do I produce graphs with polar coordinates?

Polar coordinates can be selected in the graph specification dialog boxes for histograms, scatterplots, line plots, and stacked/sequential plots (use the Options 2 tab). Categorized graphs with polar coordinates can also be produced. In addition, many standard (Cartesian) graphs can be converted into polar coordinates by selecting Polar in the Coordinate system box on the Graph: Layout tab of the Graph Options dialog box.
