The given set of points is arbitrary and not something that will be constant, given this set of points I have a need to determin the proximity which preferably would result in a bezier polygon.
My theory of approaching would be to find the northern most point and find the closest point to the east and south then working around to the west.
I think the concept you are seeking is the convex hull?

There are many algorithms to compute it, e.g., the beautiful Graham scan, for which you may find code
