The disk command creates a two-dimensional plot data object, which when displayed is a disk of radius r centered at [x,y].

The plot data object produced by the disk command can be used in a PLOT data structure, or displayed using the plots[display] command.

Remaining arguments are interpreted as options, which are specified as equations of the form option = value. For more information, see plottools and plot/options.
