Abstract : A hierarchical framework suggesting how graph readers go beyond explicitly represented data to make inferences is presented. According to our hierarchical framework, graph readers use read-offs, integration and pattern extrapolation to make inferences. Verbal protocol data demonstrates high-level differences in the way inferences are made and eye track data examines these processes at the perceptual level.
