Abstract

This paper presents an interactive technique to explain visual patterns in network visualizations to analysts who do not understand these visualizations and who are learning to read them. Learning a visualization requires mastering its visual grammar and decoding information presented through visual marks, graphical encodings, and spatial configurations. To help people learn network visualization designs and extract meaningful information, we introduce the concept of interactive pattern explanation that allows viewers to select an arbitrary area in a visualization, then automatically mines the underlying data patterns, and explains both visual and data patterns present in the viewer's selection. In a qualitative and a quantitative user study with a total of 32 participants, we compare interactive pattern explanations to textual-only and visual-only (cheatsheets) explanations. Our results show that interactive explanations increase learning of i) unfamiliar visualizations, ii) patterns in network science, and iii) the respective network terminology.

这有什么特殊含义吗?网络可视化的互动模式解释
本文介绍了一种互动技术,用于向不了解网络可视化的分析人员解释网络可视化中的视觉模式,这些分析人员正在学习如何阅读这些可视化。学习可视化需要掌握其视觉语法,并解码通过视觉标记、图形编码和空间配置呈现的信息。为了帮助人们学习网络可视化设计并提取有意义的信息,我们引入了交互式模式解释的概念,允许观众在可视化中任意选择一个区域,然后自动挖掘潜在的数据模式,并解释观众选择中的视觉和数据模式。在一项共有 32 人参与的定性和定量用户研究中,我们将交互式模式解释与纯文字解释和纯视觉解释(小抄)进行了比较。研究结果表明,交互式解释提高了对 i) 陌生可视化、ii) 网络科学模式和 iii) 相关网络术语的学习效率。
