Two 2D perspectives of a 3D plot of a motion of a ball on a string with alternating string length - shaping a motion track like a distorted "8"...
I am not finished. It's a rough sketch/doodle...It may have errors as well.
I might go into detail at explaining how I find the 3d coordinate points via my pen and paper and imagination method. This is a bit tricky. I will explain it once my focus and ability to form coherent thoughts and sentences is better again.
