The InfoVis Toolkit is a Interactive Graphics Toolkit written in Java to ease the development of Information Visualization applications and components. The main characteristics of the InfoVis Toolkit are:
Unified data structure (The base data structure is a table of columns. Columns contain objects of homogeneous types, such as integers or strings. Trees and Graphs are derived from Tables) ;
Small memory footprint (Using homogeneous columns instead of compound types improves dramatically the memory required to store large tables, trees or graphs, and generally the time to manage them).

Unified set of interactive components (Interactive filtering (a.k.a. dynamic queries) can be performed with the same control objects and components regardless of the data structure, simplifying the reuse of existing components and the design of generic ones). Fast (the InfoVis Toolkit can use accelerated graphics provided by Agile2D, an implementations of Java2D based on the OpenGL API for hardware accelerated graphics. On machine with hardware acceleration, some visualizations redisplay 100 times faster than with the standard Java2D implementation). Extensible (the InfoVis Toolkit is meant to incorporate new information visualization techniques and is distributed with the full sources and with a very liberal licence. It could be a base for student projects, reseach projects or commercial products).
