Document Summary
A simple way to determine the applicability of. If the answer is no , then the data are unstructured . If the answer is yes , then the data are structured . One of the goals of visualization might be to help discover relations among data thru visual means. The data can be represented on a graph and, one of the goals might be to explore such relations. For structured data, graphs are the fundamental structural representation of the data. Other familiar types of graphs are organizational charts, website maps as well as history browsing. In biology and chemistry, graphs are applied to molecular maps, evolutionary trees, biomedical pathways. In dynamic systems analysis, graphs are used to represent petri nets and automata, state-transition diagrams. The links between some pairs of vertices are called edges, or arcs. The size of the graph to view is a key issue in graph visualization, large graphs pose problems.
