The present invention is directed to a new visualization platform for the interactive exploration of large datasets. The present invention integrates a collection of relevant visualization techniques to provide a new visual metaphor for viewing large datasets. It is capable of providing comprehensive support for data exploration, integrating large-scale data visualization with querying, browsing, and statistical evaluation. A variety of techniques are utilized to minimize processing delays and the use of system resources, including processing pipelines, direct IO, memory mapping, and dynamic linking of 'on-the-fly' generated code.

System and method for large-scale data visualization

A system and method is provided for identifying if a document linked from a base document has changed over time. A first time and a later second time are identified. A link in a base document is recursively identified, where the link refers to a linked document. A version repository is searched to determine if the repository stores versions of the linked document associated with the first and second times. An indication is provided to the user if it is determined that a version associated with the first time and a version associated with the second time are stored in the repository.
