A Survey on Understanding Misleading Visualization, Automatic Detection, and Prevention
PhD Qualifying Examination Title: "A Survey on Understanding Misleading Visualization, Automatic Detection, and Prevention" by Mr. Yu Ho LO Abstract: Visualizations such as charts and graphs are used as a rhetorical device in news, blogs, and social media to support and further strengthen the message conveyed to the audience. Research shows the persuasive power of visualization. With equivalent information, the existence of a visualization – compared to a table – in an article has a significant effect on changing or reinforcing the reader's attitude toward the concerned matter. Misinformation on the Internet is a big challenge to every society that relies heavily on the Internet. It becomes more often that charts are included in the dissemination of misinformation. The study of misinformation on the Internet focuses on textual contents but rarely concerns the associated visual graphics. This survey looks into the current state of the art in automatic detection and prevention of misleading visualization. The efforts of the pioneers start from collecting misleading visualization to confirm their existence. Then, researchers further conducted perceptual experiments to verify the misleading effects in human perception and reasoning. Automatic detection of misleading visualization is a recent development in visualization research. Build upon the groundwork of understanding, the recent breakthrough on the detection methods of misleading visualizations makes it possible to develop prevention mechanisms like automatic correction suggestions and in-situ annotations. However, further development of this research direction requires benchmarks to compare the performance of different detection and correction methods. Besides, the current detection methods cannot be applied directly on bitmap images which is the most common format of misleading visualizations circulating on the Internet.
