Note	Any line drawn along the border of the effective window causes the
	line to be clipped, producing a line width of one-half of what it should
	be. For example, in the above plot, the lines from (0,0) to (0,1500),
	and (0,0) to (2500,0) is clipped.

Drawing Circles

The Circle (CI) command uses your current pen position as the center of the circle; you specify the radius of the circle.

The following example shows a simple command sequence using CI to draw a circle with a radius of 500 plotter units.
