欧拉图用于可视化数据并作为可视化语言的基础，是信息的有效表示，但它们可能变得混乱。先前的研究建立了一种欧拉图杂乱的测量方法，经验表明与人们如何感知杂乱相对应。然而，混乱对用户理解的影响是未知的。在三个层次的图杂乱中进行了实证研究。我们发现了一个显著的影响：通过时间和错误率来衡量，图表混乱的增加会导致性能显著下降。此外，我们发现区域（图中的一个区域）杂波对时间和错误率有显著影响。令人惊讶的是，与杂乱程度最低和最高的区域相比，杂乱程度中等的区域错误率最高。此外，答案被放置在中等杂乱区域的问题平均回答时间最长。综上所述，图杂波和带杂波都会影响欧拉图的解释。因此，未来的工作将确定单个但混乱的欧拉图是否比多个但不那么混乱的欧拉图更有效地表示信息。
Euler diagrams, used to visualize data and as a basis for visual languages, are an effective representation of information, but they can become cluttered. Previous research established a measure of Euler diagram clutter, empirically shown to correspond with how people perceive clutter. However, the impact of clutter on user understanding is unknown. An empirical study was executed with three levels of diagram clutter. We found a significant effect: increased diagram clutter leads to significantly worse performance, measured by time and error rates. In addition, we found a significant effect of zone (a region in the diagram) clutter on time and error rates. Surprisingly, the zones with a middle level of clutter had the highest error rate compared to the zones with lowest and the highest clutter. Also, the questions whose answers were placed in zones with medium clutter had the highest mean time taken to answer questions. In conclusion, both diagram clutter and zone clutter impact the interpretation of Euler diagrams. Consequently, future work will establish whether a single, but cluttered, Euler diagram is a more effective representation of information than multiple, but less cluttered, Euler diagrams.
