A demonstration of Gruff, a freely available graphical triple-store browser that attempts to make data retrieval more pleasant and powerful with a variety of tools for laying out cyclical graphs, displaying tables of properties, managing queries, and building queries as visual diagrams. Once you've created a query diagram, Gruff will generate either SPARQL or Prolog code for the query.
