Abstract Infographics range from minimalism that aims to convey the raw data to elaborately decorated, or embellished, graphics that aim to engage readers by telling a story. Several studies have shown evidence to the negative, but also positive, effects on embellishments. We conducted a set of experiments to gauge more precisely how embellishments affect how people relate to infographics and make sense of the conveyed story. By analyzing questionnaires, interviews, and eye-tracking data simplified by trail bundling, we show that, within certain bounds, embellishments have a positive effect on how users get engaged in understanding an infographic, with very limited downside. To our knowledge, our work is the first that fuses the aforementioned three information sources to understand infographics. Our findings can help to design more fine-grained studies to quantify the effects of embellishments and also to design infographics which effectively use the positive aspects identified for embellishments.

Image details: In the following we show 19 visualizations. For each visualization, we show 6 images from left to right and top to bottom: embelished visualization, embelished visualization with gaze recording, embelished visualization with gaze simplification, standardized visualization, standardized visualization with gaze recording, standardized visualization with gaze simplification.
