The Perils of Chart Deception: How Misleading Visualizations Affect Vision-Language Models
This addresses the risk of visual misinformation for non-expert users relying on VLMs, though it is incremental as it evaluates existing models without proposing new solutions.
The study tackled the problem of how misleading visualizations affect Vision-Language Models (VLMs), finding that most VLMs are deceived by deceptive chart designs, as shown by analyzing over 16,000 responses from ten models across eight types of misleading designs.
Information visualizations are powerful tools that help users quickly identify patterns, trends, and outliers, facilitating informed decision-making. However, when visualizations incorporate deceptive design elements-such as truncated or inverted axes, unjustified 3D effects, or violations of best practices-they can mislead viewers and distort understanding, spreading misinformation. While some deceptive tactics are obvious, others subtly manipulate perception while maintaining a facade of legitimacy. As Vision-Language Models (VLMs) are increasingly used to interpret visualizations, especially by non-expert users, it is critical to understand how susceptible these models are to deceptive visual designs. In this study, we conduct an in-depth evaluation of VLMs' ability to interpret misleading visualizations. By analyzing over 16,000 responses from ten different models across eight distinct types of misleading chart designs, we demonstrate that most VLMs are deceived by them. This leads to altered interpretations of charts, despite the underlying data remaining the same. Our findings highlight the need for robust safeguards in VLMs against visual misinformation.
