In the left-hand chart, points are joined by Bézier curves whose control points are randomly positioned at the same y-coordinate as the corresponding endpoint, but with x-coordinate chosen between at random the minimum and maximum distance from the control point, controlled by the *random control point minimum/maximum* inputs.

In the right-hand chart, points are joined by Bézier curves whose control points are all positioned the same distance away from the corresponding end points, controlled by the *curvature of the symmetric paths* input.
