Information Visualisation and Social Networks
Information visualisation is a research area that focuses on the use of graphical techniques to present data in an explicit form. Such static (pictures) or dynamic presentations help people formulate an understanding of data and an internal model of it for reasoning about. Such pictures of data are an external artefact supporting decision making. While sharing many of the same goals of Scientific Visualisation, Human Computer Interaction, User Interface Design and Computer Graphics, Information Visualisation focuses on the visual presentation of data without a physical or geometric form. As such it relies on research in mathematics, data mining, data structures, algorithms, graph drawing, human-computer interaction, cognitive psychology, semiotics, cartography, interactive graphics, imaging and visual design. In this talk I will present a brief history of social network analysis and visualisation, introduce layout algorithms we have developed for such visualisation and provide a detailed case study on the layout of evolving or “dynamic graphs extracted through our process of “social network inference” from large 10m records without explicit relations.
