 Since I don't know how to make animations I made a series of 12 drawings that span 2 orbits of Jupiter and 3 orbits of Hilda.  One constellation is shown to the right; .  With this series I try to show that Jupiter's Lagrange points move in orbits that overlap exactly with Jupiter's orbit, only at −60, +60 and 180 degrees angles to the planet, and that successive aphelia of Hilda coincide with L5, L4 and L3.  My 12 steps are of course very crude, but I think this principle can be animated rather smoothly.  The plot would include 5 objects travelling around the sun, of which 4 with identical orbits (Jupiter, L3, L4 and L5) and one with a smaller orbit (Hilda).  If there is no limit to the number of objects in a plot, they could just be represented by different symbols, for example big dots for Jupiter and Hilda, and circles for the Lagrange points.
