Quadrigram is an environment for data gathering, query and visualization, based on a visual programming language and intended for users with no experience programming or creating visualizations. At present, it contains 50 different visualizers.

RDF2SVG is a web-based tool from the Rhizomik initiative for transforming RDF/XML data into an SVG representation. It can also accept N-triples and N3 input, and includes a feature for filtering the user's defined preferred language from the source data.   

RelFinder is an RDF relationship discovery tool developed as part of the Visual Data Web toolset and based on the Adobe Flex open source framework. It is designed to provide an overview of RDF data through interactive visualization and exporation. Features include highlighting and filtering, and the tool permits both global and detail views. It is optimized for RDF data that provided standard SPARQL access.

Casual is a free, open source tool for generating a visualization of concepts from a key word search. It uses Wikipedia for conceptual information, and can also include Google Image search results where applicable. Users can click on a term to generate a new search from that term, while image results can be rearranged by clicking and dragging them to the desired location. Casual can produce visualizations ranging from 10 to 400 concepts in size, and can retrieve information for queries in a wide variety of languages. This tool is no longer supported; development appears to have ceased in 2009.

SemLens is a tool for visualizing and analyzing RDF data developed as part of the Visual Data Web toolset and based on the Adobe Flex open source framework. Using SPARQL to access the user's dataset, it arranges RDF data into a scatter plot which can be analyzed via semantic lenses generated based on the dataset, and with logical operators. The tool provides a global overview of the user's dataset, and can do so even for large datasets.

gFacet is a tool for graph-based visualization of RDF data developed as part of the Visual Data Web toolset and based on the Adobe Flex open source framework. Using SPARQL to access the user's dataset, it integrates filtering based on facets represented as nodes within the visualization to enable users to select which they wish to work with and create custom search interfaces.
