This is the first book devoted to both SVG and X3D as a new and universal means of visualizing information. It presents the state-of-the-art research emerging in this novel area and, to keep the book self-contained, introduces SVG and X3D fundamentals and leading authoring tools. The key topics covered include data, information, knowledge and network visualization; advanced graphical user interfaces; visualizing metadata, ontologies and the Semantic Web; new trends and paradigms in publishing and Web-based Interactive TV; displaying geographically referenced data; the advanced use of Adobe Illustrator and X3D-Edit authoring tools. This book will be essential reading not only for researchers, Web developers and graduate students but also for undergraduates and everyone who is interested in using the next-generation computer graphics on their web sites.
