Parallel Sets (ParSets) is an open source visualization app for categorical data, like census and survey data, inventory, and many other kinds of data that can be summed up in a cross-tabulation.
ParSets provide a simple, interactive way to explore and analyze such data.
ParSets has been developed using the Java programming language therefore it can be used on all operating systems that come with Java support (e.g. Mac OS X, Windows, Linux, etc.)
