Aesthetic and Practical Concerns in the Drawing of Euler and Venn Diagrams: Case Studies using SVG.
David P. Dailey · 2012
Abstract. SVG is a graphical language standardized by the World Wide Web Consortium for the display of vector graphics on the WWW. It would appear to be precisely appropriate for drawing Euler and Venn diagrams so that those drawings would scale properly to different display devices. This paper presents techniques for using SVG for doing exactly this as well as investigating a variety of aesthetic considerations that might improve the “explanatory power ” of such diagrams. Such features as the smoothness and convexity of curves, the angles and distances between their intersections, the areas of resultant regions, colors and other markings of the curves, as well has how to bring about these effects are considered. 1
