Matrix visualizations are a useful tool to provide a general overview of a graph's structure. For multivariate graphs, a remaining challenge is to cope with the attributes that are associated with nodes and edges. Addressing this challenge, we propose responsive matrix cells as a focus+context approach for embedding additional interactive views into a matrix. Responsive matrix cells are local zoomable regions of interest that provide auxiliary data exploration and editing facilities for multivariate graphs. They behave responsively by adapting their visual contents to the cell location, the available display space, and the user task. Responsive matrix cells enable users to reveal details about the graph, compare node and edge attributes, and edit data values directly in a matrix without resorting to external views or tools. We report the general design considerations for responsive matrix cells covering the visual and interactive means necessary to support a seamless data exploration and editing. Responsive matrix cells have been implemented in a web-based prototype based on which we demonstrate the utility of our approach. We describe a walk-through for the use case of analyzing a graph of soccer players and report on insights from a preliminary user feedback session.

响应矩阵单元格:用于探索和编辑多元图的焦点+上下文方法

矩阵可视化是一种有用的工具,可提供图形结构的一般概述。对于多元图,剩下的挑战是处理与节点和边相关联的属性。为了应对这一挑战,我们提出了响应式矩阵单元格作为将额外的交互式视图嵌入到矩阵中的焦点+上下文方法。响应矩阵单元是局部可缩放的感兴趣区域,为多元图形提供辅助数据探索和编辑工具。它们通过使视觉内容适应单元格位置、可用显示空间和用户任务来做出响应。响应式矩阵单元格使用户能够显示有关图形的详细信息、比较节点和边属性以及直接在矩阵中编辑数据值,而无需求助于外部视图或工具。我们报告了响应矩阵单元格的一般设计注意事项,涵盖了支持无缝数据探索和编辑所需的视觉和交互方式。响应矩阵单元已在基于 Web 的原型中实现,我们在此基础上展示了我们方法的实用性。我们描述了分析足球运动员图表的用例的演练,并报告了初步用户反馈会话的见解。
