  TOPCAT, the Tool for OPerations on Catalogues And Tables, is an interactive
desktop application for retrieval, analysis and manipulation of tabular data,
offering a powerful and flexible range of interactive visualization options
amongst other features. Its visualization capabilities focus on enabling
interactive exploration of large static local tables - millions of rows and
hundreds of columns can easily be handled on a standard desktop or laptop
machine, and various options are provided for meaningful graphical
representation of such large datasets. TOPCAT has been developed in the context
of astronomy, but many of its features are equally applicable to other domains.
The software, which is free and open source, is written in Java, and the
underlying high-performance visualisation library is suitable for re-use in
other applications.
