Journalists and visualization designers include visualizations in their articles and storytelling tools to deliver their message effectively. But design decisions they make to represent information, such as the graphical dimensions they choose and the viewer's familiarity with the content can impact the viewer's perceived credibility of charts. Especially in a context where little is known about sources of online information. But there is little experimental evidence that designers can refer to make decisions. Hence, this work aims to study and measure the effects of graphical dimensions and people's familiarity with the content on viewers' perceived chart credibility. I plan to conduct a crowd-sourced study with three graphical dimensions conditions, which are traditional charts, text annotation, and infographics. Then I will test these conditions on two user groups, which are domain experts and non-experts. With these results, this work aims to provide chart guidelines for visual designers with experimental evidence.

翻译：记者和可视化设计师在文章和叙事工具中融入可视化图表，以有效传递信息。但他们为呈现信息所做的设计选择（例如所选的图形维度以及读者对内容的熟悉程度）可能影响读者对图表可信度的感知，尤其是在网络信息来源难以查证的背景下。然而，目前缺乏可供设计师参考的实验证据。因此，本研究旨在探讨并度量图形维度及读者对内容的熟悉程度对图表可信度感知的影响。计划开展一项众包研究，设置三种图形维度条件：传统图表、文本标注和信息图，并分别在领域专家与非专家两组用户中进行测试。基于实验结果，本研究旨在为视觉设计师提供有实验证据支撑的图表设计指南。
