Algorithms for Visualizing Large Networks

Graphs are often used to encapsulate relationship between objects. Graph drawing enables visualization of such relationships. The usefulness of this visual representation is dependent on whether the drawing is aesthetic. While there are no strict criteria for aesthetics of a drawing, it is generally agreed, for example, that such a drawing has minimal edge crossing, with vertices evenly distributed in the space, connected vertices close to each other, and symmetry that may exist in the graph preserved.
