Increased access to mobile devices motivates the need to design communicative visualizations that are responsive to varying screen sizes. However, relatively little design guidance or tooling is currently available to authors. We contribute a detailed characterization of responsive visualization strategies in communication-oriented visualizations, identifying 76 total strategies by analyzing 378 pairs of large screen (LS) and small screen (SS) visualizations from online articles and reports. Our analysis distinguishes between the Targets of responsive visualization, referring to what elements of a design are changed and Actions representing how targets are changed. We identify key trade-offs related to authors' need to maintain graphical density, referring to the amount of information per pixel, while also maintaining the “message” or intended takeaways for users of a visualization. We discuss implications of our findings for future visualization tool design to support responsive transformation of visualization designs, including requirements for automated recommenders for communication-oriented responsive visualizations.

响应式可视化通信中的设计模式和权衡

对移动设备访问的增加激发了设计可响应不同屏幕尺寸的交流可视化的需求。然而，作者目前可用的设计指南或工具相对较少。我们详细描述了面向通信的可视化中的响应式可视化策略，通过分析来自在线文章和报告的 378 对大屏幕 (LS) 和小屏幕 (SS) 可视化，确定了 76 种总策略。我们的分析区分了响应式可视化的目标，指的是更改了设计的哪些元素，以及表示目标如何更改的操作。我们确定与作者需要保持图形密度相关的关键权衡，指的是每像素的信息量，同时还为可视化用户保留“消息”或预期的要点。我们讨论了我们的发现对未来可视化工具设计的影响，以支持可视化设计的响应式转换，包括对面向通信的响应式可视化的自动推荐器的要求。
