Graph Visualization is the visualization of a set of data with relations between elements. But there are many approaches to viewing such data including less obvious methods such as 3D scenes, cityscapes, nested boxes and cubes, and alternative geometries.
Graph visualization has many areas of application.
Most people have encountered a file hierarchy on a computer system. It is often necessary to navigate through the file hierarchy in order to find a particular file. Other familiar types of graphs include the hierarchy illustrated in an organizational chart and taxonomies which portray the relations between species. Web site maps are another application of graphs as well as browsing history. In biology and chemistry, graphs are applied as evolutionary trees, phylogenetic trees, molecular maps, genetic maps, biochemical pathways and protein functions.
