Abstract

Graph visualization addresses the problem of efficiently conveying the structure of relational information, which is typically modeled by networks. Therefore, graph visualization systems are largely used for information exploration and knowledge discovery, particularly in those applications that need to manage, process and analyze large (structured or unstructured) sets of data. The design of a graph visualization systems typically addresses questions that belong to the intersection of different disciplines, such as graph algorithms, data mining, software engineering, and visual analytics. In this talk I will shortly review some common and emerging graph visualization paradigms, discuss general design principles and implementation issues, and present some application examples in different domains.

Speaker's biography

Giuseppe Liotta received a PhD degree in computer engineering from the University of Rome "La Sapienza" in 1994. After two years of post-doc at Brown University, he first joined the University of Rome "La Sapienza" as assistant professor (1996-1998) and then the University of Perugia as associate professor (1999-2002). Since 2002 he is a professor of computer science at the Faculty of Engineering of the University of Perugia, where he also serves as director of the PhD School in Information and Communication Technologies. His research interests are mainly directed at the analysis and design of algorithms and systems that have applications in the fields of graph drawing, information visualization, and computational geometry. On these topics he edited special issues, wrote book chapters and surveys, published more than 130 research papers, and gave lectures worldwide. He regularly serves as PC member or as general chair of international conferences, is steering committee member of the International Symposium of Graph Drawing, member of the editorial board of Computing, and managing editor of the Journal of Graph Algorithms and Applications. During the years, his research has been funded by several public or private sponsors.
