Wellformedness Properties in Euler Diagrams: Which Should Be Used?
— Euler diagrams are often used to visualize intersecting data sets in applications such as criminology; genetics, medicine and computer file systems. One interesting aspect of these diagrams is that some data sets cannot be drawn without breaking one or more “wellformedness properties”, which are considered to reduce the user comprehension of the diagrams. However, it is possible to draw the same data with different diagrams, each of which breaks different wellformedness properties. Hence, some properties are “swappable”, so motivating the study of which of the alternatives would be best to use. This paper reports on the two empirical studies to determine how wellformedness properties affect comprehension. One study was with data, the other was with concrete data that visualized students’ enrollment on university modules. We have results from both studies that imply that diagrams with concurrency or disconnected zones perform less well than other some other properties. Fur...
