Our results do not provide significant evidence that people gain knowledge about topic diversity with word-sized visualizations faster than with the other two conditions. Further, participants who were shown word-sized visualizations performed tasks with equally few or only slightly fewer errors.Human centered computingEmpirical studies in visualizationVisualization design and evaluation methods10.2312/evp.2021106913-15
