The files provided contain stimuli, data, and analysis scripts for three online user studies. These studies investigate whether visualisations with semantic icons engage the reader more than a plain version. Engagement is measured with (1) visual attention: time spent looking at target visualisation/time spent looking at all visualisations; (2) cognitive effort: number of insights written under the target visualisation/ total number of insights, and (3) perceived engagement: self-reported engagement considering the aesthetic appeal, focused attention, perceived usability, and reward factor.
