Create a convex hull for a given set of points. The convex hull is a polygon with shortest perimeter that encloses a set of points. As a visual analogy, consider a set of points as nails in a board. The convex hull of the points would be like a rubber band stretched around the outermost nails.

WebReturns a GeoSeries of geometries representing the convex hull of each geometry. The convex hull of a geometry is the smallest convex Polygon containing all the points in each geometry, unless the number of points in the geometric object is less than three. For two points, the convex hull collapses to a LineString; for 1, a Point. WebReturn Value. Returns the minimum-area convex polygon containing this Geometry's points. Implements.
