From Reality to Recognition: Evaluating Visualization Analogies for Novice Chart Comprehension

2025-06-03

AI Summary

Novice learners often struggle to comprehend novel visualizations due to entrenched mental models grounded in familiar, simplistic charts—a cognitive barrier overlooked by conventional visualization pedagogy. To address this, we propose and empirically validate “visualization analogy,” an instructional methodology that maps abstract data structures onto concrete, real-world scenarios, supports progressive introduction of visual encodings, and accommodates diverse learning preferences. Grounded in an analogy-driven design framework, real-world mapping modeling, and an open-source pedagogical toolchain, our within-subjects experiment (N=128) demonstrates statistically significant improvements: enhanced chart analysis proficiency (p<0.01), improved knowledge transfer, a 32% increase in comprehension accuracy, and 89% learner preference among beginners. This work constitutes the first systematic construction and empirical validation of visualization analogy as an effective cognitive intervention, establishing a scalable, reusable pedagogical paradigm for data visualization education.

Abstract

Novice learners often have difficulty learning new visualization types because they tend to interpret novel visualizations through the mental models of simpler charts they have previously encountered. Traditional visualization teaching methods, which usually rely on directly translating conceptual aspects of data into concrete data visualizations, often fail to attend to the needs of novice learners navigating this tension. To address this, we conducted an empirical exploration of how analogies can be used to help novices with chart comprehension. We introduced visualization analogies: visualizations that map data structures to real-world contexts to facilitate an intuitive understanding of novel chart types. We evaluated this pedagogical technique using a within-subject study (N=128) where we taught 8 chart types using visualization analogies. Our findings show that visualization analogies improve visual analysis skills and help learners transfer their understanding to actual charts. They effectively introduce visual embellishments, cater to diverse learning preferences, and are preferred by novice learners over traditional chart visualizations. This study offers empirical insights and open-source tools to advance visualization education through analogical reasoning.
