Evaluating the Comprehension of Euler Diagrams

Florence Benoy, Peter Rodgers
2007 Information Visualisation  
We describe an empirical investigation into layout criteria that can help with the comprehension of Euler diagrams.  ...  Our work is intended to inform automatic Euler diagram layout research by confirming the importance of various Euler diagram aesthetic criteria.  ...  Many of the application areas rely on graph enhanced Euler diagrams, and so it would be useful to initiate investigations into the comprehension of these structures.  ...

How Should We Use Colour in Euler Diagrams?

Andrew Blake, Gem Stapleton, Peter Rodgers, John Howse
2014 Proceedings of the 7th International Symposium on Visual Information Communication and Interaction - VINCI '14  
This paper addresses the problem of how best to use colour in Euler diagrams.  ...  Most automated layout algorithms adopt colour fill and are, thus, reducing the effectiveness of the Euler diagrams produced.  ...  CONCLUSION In this paper we evaluated the use of colour in Euler diagrams, focusing on both curve colour and curve fill.  ...

Visualise Undrawable Euler Diagrams

Paolo Simonetto, David Auber
2008 2008 12th International Conference Information Visualisation  
Given a group of overlapping sets, it is not always possible to represent it with Euler diagrams.  ...  In order to be able to show a greater class of instances, Euler diagrams have been extended allowing more general patterns, but so far all the most common definitions cannot represent all the possible  ...  In particular, we will describe more in depth the problem of drawing Euler diagrams, and we will introduce some issues about their readability and comprehension.  ...

Visualizing Sets: An Empirical Comparison of Diagram Types [chapter]

Peter Chapman, Gem Stapleton, Peter Rodgers, Luana Micallef, Andrew Blake
2014 Lecture Notes in Computer Science  
To address this knowledge gap, this paper empirically evaluates four diagram types: Venn diagrams, Euler diagrams with shading, Euler diagrams without shading, and the less well-known linear diagrams.  ...  There are a range of diagram types that can be used to visualize sets. However, there is a significant lack of insight into which is the most effective visualization.  ...  Consequently, the prescriptive planar layout of linear diagrams, as opposed to the 'free' (disordered) positioning of curves in the other diagram types, is thought to aid comprehension.  ...
