How do I produce graphs with polar coordinates?

Polar coordinates can be selected in the graph specification dialogs for histograms, scatterplots, line plots, and stacked/sequential plots accessible from the Graphs - 2D Graphs menu (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 in the Graph: Layout options pane of the Graph Options dialog
