There's more to it, but for the sake of simplicity we'll just say I'm drawing a circle on a sheet of graph paper by filling in each square. The general idea is that I'll be filling in 3 squares, move up one, fill in 2, move up one, another 2 etc. The circumference of the circle is 201 squares on the x and y axes, and I cannot for the life of me figure out how to make the thing round without it looking really janky right in the middle of each axis. If someone could give me a formula to work with that'd be great, because then I could do this on my own from here on out.
