Layout Decisions for Tabular Euler Diagrams
摘要
Euler diagrams as a means for visualising sets and their intersections tend to be easy to learn to read but difficult or even impossible to draw. Algorithms for automated drawing exist but do not necessarily produce optimal layouts. This short paper describes a method for creating a well-readable layout for certain types of Euler diagrams. The method consists of translating an Euler diagram into an Attribute Relationship Graph (ARG) which is defined in this paper. An ARG is then evaluated by applying a set of rules using standard graph drawing software. This semi-automated method produces better layouts than automated layouts and is much faster than complete manual construction.
