Graph Visualization

Graph visualization is concerned with visual representations of graph or network data. Effective graph visualization reveals structures that may be present in the graphs, and helps the users to understand and analyze the underlying data. A graph consists of nodes and edges. It is a mathematical structure describing relations among a set of entities, where a node represents an entity, and an edge exists between two nodes if the two corresponding entities are related. A graph can be described by writing down the nodes and the edges. For example, this is a social network of people and how they relate to each other: {Andre ↔ Beverly, Andre ↔ Diane, Andre↔ Fernando, Beverly↔ Garth, Beverly↔ Ed, Carol ↔ Andre, Carol ↔ Diane, Carol ↔ Fernando, Diane ↔ Beverly, Diane ↔ Garth, Diane ↔ Ed, Farid ↔ Aadil, Farid ↔ Latif, Farid↔ Izdihar, Fernando↔ Diane, Fernando ↔ Garth, Fernando ↔ Heather, Garth ↔ Ed,
