I am trying to simulate a node graph like this where a path with 4 points (start, 2 middle, end) adapts to the movement of an object connected to the start and end:

If you move a node at the link above you can see this demonstrated. So far I've followed this tutorial using a beam but this is 2 points - not 4 - with no support for curved paths.

How can I simulate this node graph effect?

If anyone knows how to do it using expressions (and maybe the built in Beam plugin?) I'd love to know.
