applying layout algorithms to hand-drawn graphs
Hand-drawing a node-and-edge graph is a simple visual problem solving technique; however as the graph is built it can easily get untidy and confusing. It is more difficult to understand and interpret a confusing graph. By applying edge morphing techniques and a force-directed algorithm the hand-drawn graph can retain its informal appearance while its layout is improved. Graphs will be more readily understood, making the problem solving process easier.
