It occurred to me that I never described what the render shows.

The yellow circle shows the algebraic result when then data is restricted to a
small arc.   (now WAY off) The red circle is the geometric result which gives a
much more accurate result, but requires an initial "guess" for the center and
radius - which the algebraic method provides.
