Abstract
Comprehending and exploring large and complex data is becoming increasingly important for users in a wide range of application domains. Still, non-experts in visual data analysis often have problems with correctly reading and interpreting information from visualizations that are new to them. To support novices in learning how to use new digital technologies, the concept of onboarding has been successfully applied in other fields and first approaches also exist in the visualization domain. However, empirical evidence on the effectiveness of such approaches is scarce. Therefore, we conducted 3 studies: 1) Firstly, we explored the effect of vis onboarding, using an interactive step-by-step guide, on user performance for four increasingly complex visualization techniques. We performed a between-subject experiment with 596 participants in total. The results showed that there are no…
