Diagrams are two-dimensional representations of a domain in which relations among elements like points, lines, open/bounded regions on a plane match relations among the elements of that domain. Diagrams are means of surrogate reasoning, namely of exploring the possibilities to reduce or eliminate the uncertainty imparted by a problem through operations on external aids. The study of diagrams addresses formal and cognitive issues.
