在犯罪学等应用中，欧拉图经常用于可视化交叉数据集；遗传学、医学和计算机文件系统。这些图的一个有趣的方面是，一些数据集不能在不破坏一个或多个“格式良好属性”的情况下绘制，这些属性被认为会减少用户对图的理解。但是，可以用不同的图来绘制相同的数据，每个图都破坏了不同的良构性属性。因此，有些属性是“可交换的”，因此有必要研究哪种替代方案最适合使用。本文报告了两项实证研究，以确定格式良好性如何影响理解。一项研究使用抽象数据，另一项研究使用具体数据，将学生在大学模块上的入学情况可视化。我们从这两项研究中得出的结果表明，具有并发性或断开连接区域的图的性能不如其他一些属性好。此外，我们没有结果表明带有刷点的图表会对性能产生不利影响。我们的数据还表明，与具有其他属性的图表相比，非简单曲线更受欢迎。这些结果将告知人类图表设计者和自动绘图系统的开发人员使用欧拉图可视化数据的最佳方式。
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 abstract 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. Further, we have no results that imply that diagrams with brushing points adversely affect performance. Our data also indicate that nonsimple curves are preferred less than diagrams with other properties. These results will inform both human diagram designers and the developers of automated drawing systems on the best way to visualize data using Euler diagrams.
