Dex is a JavaFX application which aims to provide a general purpose framework for data visualization.  The basics are easy to learn, however Dex offers advanced capabilities in the form of SQL and groovy transformations.

Dex integrates many excellent visualization frameworks into one consistent GUI package.  This is an early release, so you are likely to find functional gaps for your particular problem space.  In such cases, you are free to extend Dex to suit your needs.
