          FORTRAN   subroutine circ(x, y, radius)

                    real x, y, radius


                    subroutine circi(x, y, radius)

     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.
