Thank you. One question, what is it we are trying to plot? The entire square? Or just the small circle?

  Hm, I guess you aren’t old enough to know what a pen plotter is. They’re drawing a line with a pen. See https://en.wikipedia.org/wiki/Plotter https://en.wikipedia.org/wiki/Plotter: “Pen plotters print by moving a pen or other instrument across the surface of a piece of paper. This means that plotters are vector graphics devices, rather than raster graphics as with other printers. Pen plotters can draw complex line art, including text, but do so slowly because of the mechanical movement of the pens. They are often incapable of efficiently creating a solid region of color, but can hatch an area by drawing a number of close, regular lines.”
