Tutorial Program


Dr. Karsten Klein, School of Information Technologies, University of Sydney, Australia

Speaker's Biography: Karsten Klein is a postdoctoral research associate at the University of Sydney, where he works on the visualization of data from real world applications. In a linkage project with Tom Sawyer Software he develops approaches that help to visually analyze and understand data from the life sciences and from social networks. He received his PhD from the University of Dortmund, Germany, and worked in the field of Graph Drawing for over ten years, with a focus on the requirements stemming from user- and application-defined constraints. He was one of the initiators and main developers for the Open Graph Drawing Framework OGDF, and was part of a research group on Graph Drawing at the research center caesar in Bonn.

Michael Newton, Founder and Director of NewtonGreen Technologies, Australia

Speaker's Biography: Michael Newton is a founder and director of NewtonGreen Technologies, a Newcastle based firm specialising in the development of data visualization and clinical trial software. He is a Product Director with Tom Sawyer Software and is currently leading the development of a .NET edition of the company's flagship product, Tom Sawyer Perspectives. Michael holds a Bachelor of Computer Science Degree with First Class Honours from the University of Newcastle, Australia.


Graph drawing deals with the computation of graph layouts in order to represent the graphs in a comprehensible and meaningful fashion. Visualizing graphs the right way can facilitate the understanding of the underlying data, and thus support the knowledge discovery process during analysis.

A huge amount of research has been done to investigate the underlying fundamentals, including questions from graph theory, computational geometry, and perception.

There exist many methods and algorithms to draw graphs in a variety of styles and for multiple application areas, and even more implementations in software libraries and customized software are available. An overview of the methods and the available software is presented in this tutorial. We will discuss the main drawing styles, and the strengths and weaknesses of the existing algorithms with a focus on large graphs. We will also consider the practical aspects, i.e. the existing software and its use for real world purposes, e.g. the analysis of social or biological networks. A software demonstration (Tom Sawyer Perspectives) will be given and a number of examples illustrate the discussion.
