Nesting in Euler Diagrams
This paper outlines the notion of nesting in Euler diagrams, and how nesting affects the interpretation and construction of such diagrams. After setting up the necessary definitions for Euler diagrams at concrete syntax and abstract levels, the notion of nestedness is introduced at the concrete level, then an equivalent notion is given at the abstract level. The natural progression to the diagr...
متن کاملCorresponding Regions in Euler Diagrams
Euler diagrams use topological properties to represent settheoretical concepts and thus are ‘intuitive’ to some people. When reasoning with Euler diagrams, it is essential to have a notion of correspondence among the regions in different diagrams. At the semantic level, two regions correspond when they represent the same set. However, we wish to construct a purely syntactic definition of corres...
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 کاملAbstractions of Euler Diagrams
ions of Euler diagrams Andrew Fish 1,2 Jean Flower 1 Visual Modelling Group University of Brighton Brighton BN2 4GJ, UK Abstract Euler diagrams are a graphical means to represent information. Providing an abstraction captures the pertinent information precisely, ignoring irrelevant details (where relevancy is dependent upon the application domain). We present two new abstractions and show that ...
متن کاملConjunction Labels in Euler Diagrams
Sometimes Euler diagrams [1] and notations based on them such as spider diagrams [5] can become very cluttered and difficult to read. We are therefore interested in extensions to the basic Euler diagram notation that can reduce clutter in a diagram, increase its clarity and allow us to focus only on relevant details. There are many ways to do this. The simplest is probably to restrict the numbe...
