||Information visualizations with multiple coordinated views enable users to rapidly explore complex data and discover relationships. However, it is usually difficult for users to find or create the coordinated set of visualizations they need. Snap-Together Visualization allows users to coordinate visualizations to create customized multiple-view interfaces. Users query their relational database and load results into desired visualizations. Then they specify coordinations between visualizations for selecting, navigating, or re-querying. Developers can make independent visualization tools Ôsnap-able' by including a few simple hooks.
