Visualization over the World Wide Web

The Web has grown from being a global information repository into a worldwide distributed computing environment. This offers the opportunity to carry out data visualization as a Web-based application. In this paper we look at the different players involved in the creation of a Web-based visualization service, and hence build a reference model for Web-based visualization. we then use this model to identify three distinct system architectures for Web-based visualization. We illustrate each architecture with corresponding examples of visualization services.
