“…A prolific field is Scientific Visualization, providing related architectures. [13] introduced a client/server communication based on a simple reference model to perform data visualization. The visualization is done over the web, and focuses only on a specific data type which are plots.…”

Abstract. In this paper, we detail specifications of a Visualization On-Demand (VizOD) server. We show that packaging information visualization processes into services reachable over a network benefits both users and programmers, by reducing development cycles. We implemented a prototype based on our architecture, resulting in an innovative way to visually explore large movie database. We discuss early results and our main perspective is to federate a community of users and practitioners to better design interactive environments and understand users behaviors.

“…An early example of this approach was the work of Wood et al [3] in 1996: they demonstrated an air quality application in which a user selected data of interest using a web form; a CGI script was invoked to retrieve the data from a database and run a dataflow visualization system (IRIS Explorer [13]) on a server; and a 3D visualization was returned in the form of a VRML scene. We use exactly the same application to demonstrate the web services architecture proposed in this paper, in order to illustrate the advances that have appeared in the last twelve years thanks to the development of modern web service technologies.…”

Abstract-Service-oriented architectures are increasingly being used as the architectural style for creating large distributed computer applications. This paper examines the provision of visualization as a service that can be made available to application designers in order to combine with other services. We develop a three-layer architecture: a client layer which provides the user interface; a stateful web service middleware layer which provides a published interface to the visualization system; and finally, a visualization component layer which provides the core functionality of visualization techniques. This separation of middleware from the visualization components is crucial: it allows us to exploit the strengths of web service technologies in providing standardized access to the system, and in maintaining state information throughout a session, but also gives us the freedom to build our visualization layer in an efficient and flexible way without the constraints of web service protocols.We describe the design of a visualization service based on this architecture, and illustrate one aspect of the work by re-visiting an early example of webbased visualization.

“…This is followed by a brief examination of how each technique works in practice, its implementation requirements, its relative advantages and disadvantages, and any other issues peculiar to the technique. Wood et al (1996) and MacEachren (1998) identified four distribution styles for Web-based geographic visualization software. The data server style is where the server only supplies raw data, and manipulation, display and analysis all take place at the client, so this is primarily a client-side processing model, as illustrated in Fig.…”

“…MacEachren (1998) calls this the "3D model interaction" style, but this does not really fit the current context. Wood et al (1996) originally applied this distribution style to VRML models for GIS applications, but it could be applied to any interactive model that is generated at the server, then downloaded to and manipulated at the client. "Model interaction environment" therefore seems a more appropriate name.…”

Scalability of Techniques for Online Geographic Visualization of Web Site Hits

Extremely large data sets are now commonplace, and they are often visualized through the World Wide Web. Scalability of web-based visualization techniques is thus a key issue. This paper investigates the scalability of four representative techniques for dynamic map generation and display (e.g., for visualizing geographic sources of web site hits): generating a single composite map image, overlaying images on an underlying base map and two variants of overlaying HTML on a base map. These four techniques embody a mixture of different display technologies and distribution styles (three server-side and one distributed across both client and server). Each technique was applied to 20 synthetic data sets of increasing size, and the data set volume, elapsed time and memory consumption were measured. The results show that all four techniques are suitable for small data sets comprising a few thousand points, but that the two HTML techniques scale to larger data sets very poorly across all three variables.
