Architecture of a software system for scientific data visualisation

In this paper, after an enumeration of software for scientific computation and data visualisation, we give a set of demands for this sort of software. We discuss the architecture of a scientific data visualisation software system entitled "Graph Server" which was designed and developed by the authors. The examples of 2D/3D hodograph curve, 2D/3D histogram, 3D surface and 2D area are presented.
