Chartography: A Benchmark for Professional Chart Understanding

Chartography is introduced as a novel benchmark designed to evaluate professional graphical reasoning skills, particularly focusing on whether advanced AI models can interpret specialized charts commonly used across fields like medicine, engineering, finance, and science. Unlike traditional benchmarks which focus on simple chart types such as bar or line graphs, Chartography includes complex formats like Sankey diagrams, candlestick charts, and contour maps, requiring models to perform tasks like estimating unlabeled values and interpreting complex geometries. Despite the capabilities of frontier models, which perform well on existing benchmarks, they struggle with Chartography, scoring below 50% due to challenges in visual estimation and domain-specific conventions. The benchmark emphasizes the importance of precise visual reasoning and expert grading tailored to the complexities of professional chart reading, highlighting the gap between current AI capabilities and the nuanced skills required for interpreting professional charts.
