Filtergraph is a web application for transforming datasets into interactive portals that can help bring meaning to big data. While it is designed to handle astronomy data, Filtergraph can be easily configured for a wide variety of data sources. Filtergraph is optimized for speed: for instance, operations on a stellar database of 3.1 million entries executes in less than 2 seconds.
