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.</ABSTRACT><URL>http://portal.acm.org/citation.cfm?id=1324933</URL></RECORD></RECORDS></XML>
