This book presents the state of the art in software visualization and thus attempts to establish it as a field on its own. Based on a seminar held at Dagstuhl Castle in May 2001 the book offers topical sections on: algorithm animation software visualization and software engineering software visualization and education graphs in software visualization and perspectives of software visualization. Each section starts with an introduction surveying previous and current work and providing extensive bibliographies.
