1. A computer readable storage medium, comprising executable instructions to: convert a Venn diagram into a temporary graph; create a dual graph from the temporary graph; remove a first vertex and a set of edges incident upon the first vertex from the dual graph, wherein the first vertex corresponds to the highest order intersection of the Venn diagram; and replace a second vertex with the first vertex to create a new graph, wherein the second vertex represents a universe of the Venn diagram, wherein the universe represents an outer infinitely large region associated with the Venn diagram.
