DESCRIPTION

circ outlines a circle.  The circle has a center at point (x,y) and a radius (radius), which are specified in world coordinates.  Since a circle is a 2-D shape, these routines have only 2-D forms (note that circles rotated outside the 2-D x-y plane appear as ellipses).  The circle is in the x-y plane, with z=0.  The system draws the circle using the current color, linestyle, linewidth, and writemask.
