Members of IVRG are strongly involved with NICTA's VALACON (Visualisation and Analysis of Large and Complex Networks) project.

Many discrete scientific models are relational, that is, they consist of a set of entities and the relationships between them. When such models are small and simple, they can be analyzed by hand; however, increased data availability has led to many large and complex relational models. Examples include:

The key scientific challenges of this project include scalability, visual complexity, good integration with analysis methods, effective 3D visualisation and navigation issues. This project aims to design and implement systems to enhance human understanding of such networks.

Project Overview


To design, implement and evaluate a new, integrated framework of graph drawing algorithms in 2D and 3D for visualisation of large, complex networks.

Key Points:


VALACON is led by Dr. Seokhee Hong, with several researchers and PhD students.
