Abstract:

 When drawing graphs whose edges and nodes both contain text or graphics, such information needs to be displayed without overlaps, either as part of the initial layout or as a post-processing step. The core problem in removing overlaps lies in retaining the structural information inherent in a layout, minimizing the additional area required, and keeping edges as straight as possible. This paper presents a combined node and edge overlap removal algorithm that aims
at offering one solution to this problem, based on minimizing a cost function that both reduces topological changes to the original drawing, and  keeps edges straight.
