Closed Curve as boundary for random points on a plane

I can create (sort of) a set of random points on a plane in GH. I can use that to create a set of randomly placed spheres on that plane. What i have not been able to do is to put a closed curve as a boundary around a subset of those components. What components/programming would be suggested to accomplish this? the goal is to create a random set of multi-sized spherical divots on a flat object the shape of the closed curve. Thanks for any guidance… Carl H
