Abstract
Well-designed visualizations can leverage the strength of our perceptual capabilities and augment viewers’ cognition to help find insights about data, facilitate content comprehension, and enable informed decision-making. However, poor visualizations can obstruct the understanding of the content and can even bias viewers’ data interpretation and analysis. In this context, visualization serves as a medium between viewers and the information being conveyed, enhancing the message's credibility. This dissertation focuses on developing a better understanding of how combinations of different design choices affect viewers' perceived message credibility in visualization. It is comprised of three high-level goals:
• Identify embellishment factors that influence perceived credibility: We identify factors that contribute to shaping viewers' perceived credibility for communicated messages (embellishment: color, imagery, or stylized fonts and shapes) in visualizations.
• Quantify effects of embellishment factors in perceived credibility: We conduct crowdsourced studies to quantify the effects of design choices that shape people's perception of message credibility.
• Provide design guidelines: We provide design guidelines that suggest ways that visualizations might leverage embellishment to effectively communicate engaging messages without degrading perceived message credibility.
