DARLS: differencing and merging diagrams using dual view, animation, re-layout, layers and a storyboard

Abstract

We present a new system for visualizing and merging differences in diagrams. It uses animation, dual views, a storyboard, relative re-layout, and layering to visualize differences. The system is also capable of differencing UML class diagrams. An evaluation produced positive results for animation and dual views with difference layer.
