Catenary: The Hanging Chain (II)

Catenary is formed by a hanging flexible chain, suspended at ends and carrying only its own weight.

Galileo Galilei (ca. 1600) believed that the chain would be a parabola. He wasn't right, yet he was close. Move the end points and change the length within reasonable limits, while toggling among plots of catenary, parabola and their magnified absolute difference.
