Abstract

Understanding and consuming public budget data is a key issue, helping citizens in gaining insight into their democratic and political systems. The goal of this work is to present Waffster, a user-friendly representation supporting the understanding of such data. The proposed representation enables the browsing, searching, comparing, and presenting of the hierarchically arranged components and quantities in budgets. In this paper, we first conduct a thorough survey of online public budget visualizations. Then, in collaboration with Le Devoir, a Canadian daily newspaper, we propose a novel unit-based hierarchical design based on waffle charts. We evaluate this design using a controlled user study to compare it to a tree-map based layout, and a case study conducted with Le Devoir during the provincial election campaign in Québec of 2018.

华夫饼:用于预算可视化的分层华夫饼图
理解和使用公共预算数据是一个关键问题,可以帮助公民深入了解他们的民主和政治制度。这项工作的目标是提出Waffster,一个用户友好的表示支持这些数据的理解。所建议的表示支持浏览、搜索、比较和呈现预算中按层次排列的组件和数量。在本文中,我们首先对在线公共预算可视化进行了彻底的调查。然后,我们与加拿大日报Le Devoir合作,提出了一种基于华夫饼图的新颖的基于单位的分层设计。我们通过一项受控用户研究来评估这一设计,将其与基于树图的布局进行比较,并在2018年青海省选举期间与Le Devoir进行了案例研究。
