IVPrototype is an Information Visualization Prototype for the visualization of both geometrical and non-geometrical data. Our goal is to provide a generic system that automatically generates data visualization and dynamically adapts the interface according to the data in order to control the amount of information displayed. The information is organized in one or several information groups, which aggregate semantically related information. Icons and coloured surfaces are the visual mappings provided. Other features of this prototype are: a data independent architecture; several filtering mechanisms; use of degree of interest functions; automatic selection of icons based on scale factor and semantic criteria.
