A javascript function that takes a list of points and calculates a curvy path that passes all these points. See https://hartmut-bohnacker.de/projects/points-to-curve for more information.
// Calculates a curve that goes through a number of points.
// There are lots of mathematical approaches to do so
// (see: https://en.wikipedia.org/wiki/Cubic_Hermite_spline).
// The most commonly used seems to be the Catmull–Rom spline.
// My approch here is not intended to be a new general
// solution to this problem, but it should fit some geometrical
// and graphical needs. See
// https://hartmut-bohnacker.de/projects/points-to-curve
// for more explanation.
