In the 17th century, the Cartesian coordinate system exposed the unity between algebra and geometry, accelerating the development of the math that took humans to the moon.

Although data visualizations are a relatively recent invention, most people are expected to know how to read them. How do current machine learning systems compare with people when performing tasks involving data visualizations? Prior work evaluating machine data visualization understanding has relied upon weak benchmarks that do not resemble the tests used to assess these abilities in humans. We evaluated several state-of-the-art algorithms on data visualization literacy assessments designed for humans, and compared their responses to multiple cohorts of human participants with varying levels of experience with high school-level math. We found that these models systematically underperform all human cohorts and are highly sensitive to small changes in how they are prompted. Among the models we tested, GPT-4V most closely approximates human error patterns, but gaps remain between all models and humans. Our findings highlight the need for stronger benchmarks for data visualization understanding to advance artificial systems towards human-like reasoning about data visualizations.
