Introduction to Network Visualization

A network refers to an object composed of elements and relationships or connections between those elements.

Network analysis is a collection of techniques for examining the relationships between entities, and depicting the structure of those relationships. Network analysis spans a number of domains, including social networks, bibliometrics, epidemiology, bioinformatics, complex systems, and text analysis.

Graph theory provides the formal basis for network analysis, across domains, and provides a common language for describing the structure of networks.

Network visualization involves the visualization of the relationships (edges or links) between data elements (nodes).
