When Charts Deceive Web Agents: A Paired Benchmark for Misleading Visualization-Grounded Tasks

Read the original on arXiv Computation and Language →

The paper introduces MisVisAgentBench, a paired benchmark with 280 task instances that compare clean versus misleading chart evidence for web agents. It evaluates how deceptive visualizations affect agent execution, providing a diagnostic framework to separate misleading-induced failures from baseline difficulty. Results show that misleading charts reduce task success by over 34 percentage points and tend to redirect agents toward targeted misleading actions.

Chart Deception in Vision-Language Models: From Vulnerability to Mitigation

arXiv:2607. 22600v1 Announce Type: new Abstract: Information visualizations are widely used to communicate patterns, trends, and outliers, yet deceptive design choices-such as truncated or inverted axes, distorted aspect ratios, inappropriate encodings, and misleading color mappings-can systematically alter interpretation while preserving the underlying data.
