all other points have a negative x coordinate, and the x range passed to the tessellation algorithm is [-124, −71]. You probably forgot the minus sign for that point’s x coordinate.
as mentioned above, the algorithm fails to converge because the weights are poorly scaled. For a better graphical representation, you will want to scale them to the range between one and one half of the nearest point distance, but to make it run, just increase the division constant.
