Simplex graph

A Simplex graph is related to the concept of simplices in geometry and topology. In mathematical terms, a simplex is the generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. For example: - A 0-simplex is a single point. - A 1-simplex is a line segment connecting two points. - A 2-simplex is a triangle, defined by three points. - A 3-simplex is a tetrahedron, defined by four points.
