spiral

The same circuit walked more than once, drawn as a path that moves outward or inward on every turn. A circle says the loop repeats. A spiral says the loop repeats and something is different each time around, with the radius carrying the quantity that changed. It is the cleanest way to show that a repeating process is not going in circles after all.

Example

Best when the loop is real but the level is not the same on each pass, whether it is climbing or sinking.
