    "subtitle": null,
    "abstract": "We are currently in the process of designing and implement-\ning a computational cognitive system that combines percep-\ntion, memory, attention, and domain-specific semantic knowl-\nedge to perform data visualization tasks. While this work is\nstill in early stages, we report here on one subset of this larger\nproject that involves building a “visual long term memory” for\nthe system. To constrain the problem, we assume a domain\nof astronomy, and we focus exclusively on scatterplot visual-\nizations. In this paper, we present three of our initial steps\nalong this path. First, we collected and analyzed a catalog of\n74 scatterplots from real astronomy sources (papers, books,\netc.), which we consider to be typical data visualizations that\nastronomers would frequently encounter during their educa-\ntion. Second, we asked a team of human raters to rate all\n74 scatterplots along nine dimensions describing shape cate-\ngories, taken from a computational approach originally sug-\ngested by John and Paul Tukey called scagnostics. Third, we\ncalculated computer-based scagnostics for a subset of the scat-\nterplots. We measured inter-rater agreements among the hu-\nman raters and between the calculated and human ratings.",
