Convex Hull

A convex hull is the smallest convex shape that completely encloses a set of points in a plane. Imagine stretching a rubber band around the outermost points; when you release it, the band tightens around them, forming a boundary that contains all the points inside. This boundary is the convex hull. It’s useful in areas like computer graphics, pattern recognition, and geographic mapping to simplify complex shapes, find boundaries, or analyze point distributions efficiently.
