Perceptually-Guided Analysis of Aggregation

Drawing on the methodology of perceptual psychology, we are how viewers build up big pictures from data to determine if novel encodings can outperform standard designs for the affordance of quick summarization and comparison of data sets. By letting viewers build up the big picture themselves, we can promote better patterns of decision-making, and let people reason about data even when pixels are a limited resource.
