Preserving the Hand-drawn Appearance of Graphs

When using a sketching tool to draw graphs, the edges need to appear hand-drawn. This is particularly the case after edges have been repositioned – if the action of moving a node results in its edges appearing as straight lines, the graph drawing will not retain its informal, hand-drawn appearance. The method for preserving the hand-drawn appearance of graphs described here is based on user observations and takes into account the context of the edge. The effectiveness of this algorithm was validated with a user study which suggests that people cannot distinguish the generated edges from hand-drawn edges. 1.
