The obvious drawbacks of this development are highlydependent software systems, which are only available for a restrictednumber of users. Today, due to the remarkable advances in hardware andsoftware technologies, not only very expensive graphics workstations,but also low-cost PCs are capable of running computational demandingvisualization systems. Furthermore, the rapid development of the mediumWorld Wide Web along with state-of-the-art Internet programmingtechniques has led to a trend toward more generally usable visualizationsystems. In this paper, we propose a functional developer's frameworkfor general Web-based visualization systems which makes intelligent useof application specific software and hardware components on the serverside, as well as Java's benefits on the client side. To demonstrate theframework's abilities, we have applied it to two practical visualizationtasks and report on our experience concerning practicability andpitfalls 收起
