Visual Browser is a Java application for visualizing a graph of RDF data. When you mouse over a link, a popup window shows the details. Visual Browser uses Jena to access the data from a file or database and both MySQL and Postgres are supported. The visualization can be modified by a perspective file, encoded in XML, that can specify the colors and shapes for different types of nodes, the nodes to hide, lables for properties, etc. Visual Browser uses the open sourced TouchGraph tools for graph-based interfaces.
