Nested Venn Diagrams
Nesting is used to extend Venn Diagrams from their usual practical limit of three or four sets to a form that readily handles five to eight sets. Although devised independently, such nested diagrams can be viewed as the application to Venn Diagrams of an idea proposed in 1896 by Lewis Carroll, in the context of his alternative set diagrams. Such nesting is rarely if ever used today, but has gen...
متن کاملMinimum Area Polyomino Venn Diagrams
Polyomino Venn (or polyVenn) diagrams are Venn diagrams whose curves are the perimeters of polyominoes drawn on the integer lattice. Minimum area polyVenn diagrams are those in which each of the 2n intersection regions, in a diagram of n polyominoes, consists of exactly one unit square. We construct minimum area polyVenn diagrams in bounding rectangles of size 2r×2c whenever r, c ≥ 2. Our const...
متن کاملVenn Diagrams with Few Vertices
An n-Venn diagram is a collection of n finitely-intersecting simple closed curves in the plane, such that each of the 2n sets X1∩X2∩· · ·∩Xn, where each Xi is the open interior or exterior of the i-th curve, is a non-empty connected region. The weight of a region is the number of curves that contain it. A region of weight k is a k-region. A monotone Venn diagram with n curves has the property t...
متن کاملProjections in Venn-Euler Diagrams
Venn diagrams and Euler circles have long been used to express constraints on sets and their relationships with other sets. However, these notations can get very cluttered when we consider many closed curves or contours. In order to reduce this clutter, and to focus attention within the diagram appropriately, the notion of a projected contour, or projection, is introduced. Informally, a project...
متن کاملVenn and Euler Data Diagrams
Scientists conducting microarray and other experiments use Venn and Euler diagrams to analyze and illustrate their results. Most existing computer programs that implement Venn and Euler diagrams are limited to three sets. The few programs that plot more than three sets rest on ad-hoc methods, such as force-directed algorithms designed for laying out graphs. As a general solution to this problem...
