Ah, Peter, you are a very bad boy!  ~(:>))  At first I thought you had
deliberately inserted a subtle teaching point that I was supposed to
detect and correct.  When I failed to find some subtlety of OOP or
MVC, I switched to looking at the actual display of the circle.  So I
improved how it looked on my PC, but realized this was not a general
solution and left it there.

I think I have played with ASCII art enough for now.  And your code
did give me (two) good examples demonstrating an implementation of
MVC, which was the main point of the thread.  I am content (For a
moment at least!).

Thanks!
