The point `p0` controls the movement of the line. The coordinates of `p0` define a transformation (translation). This transformation is applied to the points `p1` and `p2`. which in turn define the line to be animated. Of course, in applications `p0` should be hidden

const board = JXG.JSXGraph.initBoard(BOARDID, {

function startAnimation() {
