Actually, it doesn't "assume" any shape at all. It computes a Delaunay
triangulation of a set of points irrespective of any boundary edges that you
might have wanted. That's what an (unqualified) Delaunay triangulation is.
Docstrings are not the place for tutorials on basic concepts. Google works quite
