The circle command creates a two-dimensional plot data object, which when displayed is a circle of radius r centered at c.

To create a filled circle, use plottools[disk] instead.

The plot data object produced by the circle 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.
