Questions tagged [graph-visualization]

Graph visualisation is concerned with the rendering of mathematical graphs (collections of nodes and edges) on a screen, either theoretically or using an existing software package. Because most graphs are not "planar" (cannot be drawn without edges crossing), most graph visualisation algorithms must rely on heuristics that balance compactness against minimisation of edge crossings and that produce aesthetically appealing renderings.
