I see plenty of solutions for plotting spirals/curves based on an angle, but is there a way to plot a curve based on a changing radius? For example, the distance between the point that is "tracing" and the point it is tracing around starts at 20 meters, but decreases to 0 meters over 1 second then increases back to 20 meters over 1 second. The point is rotating at pi/2 rad/s, so it should complete 180-deg in the 2 seconds. I have no idea what this would look like, which is why I am trying to plot it.
