Significantly, it could be argued that beauty always maintains an underlying sense of disability and that increasing this sense over time may actually renew works of art that risk to fall out of fashion because of changing standards of taste. It is often the presence of disability that allows the beauty of an art work to endure over time. Would the Venus de Milo still be considered one of the great examples of both aesthetic and human beauty if she still had both her arms? Perhaps it is an exaggeration to consider the Venus disabled, but René Magritte. | Which Aesthetic Has the Greatest Effect on Human Understanding Helen Purchase Department of Computer Science and Electrical Engineering The University of Queensland Australia Abstract. In the creation of graph drawing algorithms and systems designers claim that by producing layouts that optimise certain aesthetic qualities the graphs are easier to understand. Such aesthetics include maximise symmetry minimise edge crosses and minimise bends. A previous study aimed to validate these claims with respect to three aesthetics using paper-based experiments 11 The study reported here is superior in many ways five aesthetics are considered attempts are made to place a priority order on the relative importance of the aesthetics the experiments are run on-line and the ease of understanding the drawings is measured in time as well as in the number of errors. In addition greater consideration is given to the possible effect of confounding factors in the graph drawings. The results indicate that reducing the number of edge crosses is by far the most important aesthetic while minimising the number of bends and maximising symmetry have a lesser effect. The effects of maximising the minimum angle between edges leaving a node and of fixing edges and nodes to an orthogonal grid are not statistically significant. This work is important since it helps to demonstrate to algorithm and system designers the aesthetic qualities most important for aiding human understanding the most appropriate compromises to make when there is a conflict in aesthetics and consequently how to build more effective systems. 1 Introduction Automatic graph drawing algorithms produce a diagram which represents an underlying graph structure. The aim of the layout process is to depict relational information in a form that makes it easier to read understand and use. Designers of such algorithms ensure that certain aesthetics are optimised and claim that by doing do the resultant graph drawing helps the human reader
