Draw curve around the outer points of a list of points


It looks fairly (and probably is) but I cant find out.
I would like to draw a curve around a cloud of points.

The hull command only select the outer 4 corner points.

any suggestions?

Convex Hull is named convex for a reason…

I googled for concave hull and found this:

If you want to draw a curve around the outer points, you can use Metaball. The resulting curve will not go through the points however.
