A transmogrifier is a novel interface that enables quick, on-the-fly graphic transformations. An image region can be specified by a shape and transformed into a destination shape with real-time visual feedback. Both origin and destination shapes can be circles, quadrilaterals, or arbitrary shapes defined through touch. Transmogrifiers are flexible, fast, and simple to create and invite use in casual InfoVis scenarios, opening the door to alternative ways of exploring and displaying existing visualizations (e.g., rectifying routes or rivers in maps), and enabling free-form prototyping of new visualizations (e.g., lenses).
