“…We investigate the potential role of facilitation across lower-level task taxonomies, e.g., Brehmer and Munzner (2013) and more sophisticated models of visual analytics (Andrienko et al, 2018). Specific instantiations of guidance have been reported, for example, helpful interventions when eye-tracking indicates an analyst is exhibiting signs of confusion (Conati et al, 2013;Toker and Conati, 2014;Panwar and Collins, 2018) or when a logging system detects sub-optimal search strategies (Brown et al, 2014). There have also been investigations into the role of machine intelligence in revealing a potential bias in an analysis process (Wall et al, 2017a), by exposing the differences between the data a user has seen and the overall characteristics of the full dataset.…”
