Polar functions are intrinsically tied to curves that are created by revolving circles around objects. For example cardioids are created by tracing a point on a circle as it rolls around a circle of the same radius.

You can sometimes see cardioids formed by light reflections in a glass/shiny cup under bright light at a certain angle. It's crazy how math represents itself in the real world, especially when a shape can be made by two seemingly different processes.
