People have been asking me lately, "how do you make such perfect circles", I tell them "World Edit" and naturally they give the -.- face. But like the rest of us, there was a period where not everyone had such luxurious tools such as World Edit. So before I had world edit I used this graph to make my circles. I now pass my knowledge down to someone that can carry out my odyssey.

Well, imaging seems to be broken so heres a link
