Visualization literacy,the ability to interpret and comprehend visual designs,is recognized as an essential skill by the visualization community.We identify and investigate barriers to comprehending parallel coordinates plots(PCPs),one of the advanced graphical representations for the display of multivariate and high-dimensional data.We develop a parallel coordinates literacy test with diverse images generated using popular PCP software tools.The test improves PCP literacy and evaluates the user’s literacy skills.We introduce an interactive educational tool that assists the teaching and learning of parallel coordinates by offering a more active learning experience.Using this pedagogical tool,we aim to advance novice users’parallel coordinates literacy skills.Based on the hypothesis that an interactive tool that links traditional Cartesian Coordinates with PCPs interactively will enhance PCP literacy further than static slides,we compare the learning experience using traditional slides with our novel software tool and investigate the efficiency of the educational software with an online,crowdsourced user-study.User-study results show that our pedagogical tool positively impacts a user’s PCP comprehension. 展开更多
