[Code is in the comments] I wrote a instructions that makes a circle, and can fill it too, without the worry of if its obscured, or slightly off screen, I know its not revolutionary, I just want everyone to know about it, so they can comfortably use circles anywhere.

Here is the code, its pretty simple actually,which would make sense, since its just circles. If F is set to 0, the circle is not filled. If F is set to 1, then the circle is filled.
