Learn about an alternative approach to determining the relative worth of graph layout aesthetics, based on how users create their own graph drawings, as part of the CIDSE Fall 2017 Invited Talk Seminar Series. Senior Lecturer Helen Purchase will present the results of both the published research experiments, as well as two follow-up studies.

Abstract

Much effort has been spent designing algorithms for the automatic layout of graphs. Typically, the worth of these algorithms has been determined by their computational efficiency and by the extent to which the graph drawings they produce conform to pre-defined “aesthetics” (for example, minimizing the number of edge crosses and edge bends, or maximizing symmetry).

Prior experimental work has focused on the extent to which the layout of a graph drawing assists with the comprehension of the embodied relational information.

This seminar presents an alternative approach to determine the relative worth of graph layout aesthetics, based on how users create their own graph drawings.

About the speaker

Helen Purchase is Senior Lecturer in the School of Computing Science at the University of Glasgow.

Purchase has worked in the area of empirical studies of graph layout for several years, and has research interest in visual aesthetics, task-based empirical design, collaborative learning in higher education and sketch tools for design.
