可视化中的设计特定变换

Design-Specific Transformations in Visualization

Eugene Wu, Remco Chang

AI总结:

本文提出将设计特定变换纳入信息可视化参考模型,并用函数组合形式化用户任务,以支持分析数据变换、推理可视化正确性与有效性。

摘要:

在可视化中,将原始数据转换为视觉上可理解的表示形式的过程至关重要。虽然现有的模型(如信息可视化参考模型)描述了数据到可视映射的过程,但它们往往忽略了一个关键的中间步骤:设计特定变换。该过程发生在数据变换之后、可视数据映射之前,进一步派生数据,例如分组、布局和统计信息,这些对于正确呈现可视化至关重要。在本文中,我们主张对设计特定变换进行更深入的探索,强调它们在理解可视化属性方面的重要性,特别是与用户任务相关的重要性。我们将设计特定变换纳入信息可视化参考模型,并提出一种新的形式化方法,将用户任务作为数据上的函数来涵盖。由此产生的形式化方法相比现有可视化模型具有三个关键优势:(1)将任务描述为函数的组合,(2)支持对可视数据映射的数据变换进行分析,以及(3)增强关于可视化正确性和有效性的推理能力。我们进一步讨论了该模型对可视化理论和可视化实验设计的潜在影响。

英文摘要:

In visualization, the process of transforming raw data into visually comprehensible representations is pivotal. While existing models like the Information Visualization Reference Model describe the data-to-visual mapping process, they often overlook a crucial intermediary step: design-specific transformations. This process, occurring after data transformation but before visual-data mapping, further derives data, such as groupings, layout, and statistics, that are essential to properly render the visualization. In this paper, we advocate for a deeper exploration of design-specific transformations, highlighting their importance in understanding visualization properties, particularly in relation to user tasks. We incorporate design-specific transformations into the Information Visualization Reference Model and propose a new formalism that encompasses the user task as a function over data. The resulting formalism offers three key benefits over existing visualization models: (1) describing task as compositions of functions, (2) enabling analysis of data transformations for visual-data mapping, and (3) empowering reasoning about visualization correctness and effectiveness. We further discuss the potential implications of this model on visualization theory and visualization experiment design.
