摘要

基因组学专家依靠可视化从复杂和大规模的数据集中提取和分享见解。除了用于数据探索的现成工具之外,越来越需要帮助专家编写定制可视化的平台,以进行探索和交流见解。已经提出了各种用于编写数据可视化的交互技术,例如模板编辑、架子配置、自然语言输入和代码编辑器。然而,目前尚不清楚基因组学专家如何创建可视化,以及哪种技术最能支持他们的可视化任务和需求。为了解决这一差距,我们与基因组学研究人员进行了两项用户研究:(1)半结构化访谈(n=20),以确定任务、用户上下文和当前的可视化创作技术;(2)一项探索性研究(n=13),使用视觉探针来引出用户在创建可视化时的意图和所需技术。我们的贡献包括(1)描述可视化创作目前如何在基因组可视化中使用,根据创作工具的共同标准确定局限性和优点,以及(2)基于我们对创作技术的任务和用户特定有用性的发现,基因组可视化创作工具的一般设计含义。所有补充材料可在https://osf.io/bdj4v/上获得

Understanding Visualization Authoring Techniques for Genomics Data in the Context of Personas and Tasks
Genomics experts rely on visualization to extract and share insights from complex and large-scale datasets. Beyond off-the-shelf tools for data exploration, there is an increasing need for platforms that aid experts in authoring customized visualizations for both exploration and communication of insights. A variety of interactive techniques have been proposed for authoring data visualizations, such as template editing, shelf configuration, natural language input, and code editors. However, it remains unclear how genomics experts create visualizations and which techniques best support their visualization tasks and needs. To address this gap, we conducted two user studies with genomics researchers: (1) semi-structured interviews (n=20) to identify the tasks, user contexts, and current visualization authoring techniques and (2) an exploratory study (n=13) using visual probes to elicit users' intents and desired techniques when creating visualizations. Our contributions include (1) a characterization of how visualization authoring is currently utilized in genomics visualization, identifying limitations and benefits in light of common criteria for authoring tools, and (2) generalizable design implications for genomics visualization authoring tools based on our findings on task- and user-specific usefulness of authoring techniques.
