Abstract
We discuss the results of a comparison between human judgments of visualization readability and an automatic assessment based on empirically-derived design guidelines. The result of this comparison is important for understanding how automated applications of empirically derived guidelines might complement subjective human judgments. To achieve this goal, we compare scores from Draco 2, a comprehensive test suite that includes an underlying model of visualization guidance, against subjective participant scores from the PREVis Layout readability scale. Our results show that the automatic scores were not a good predictor of human judgment of layout readability.
