Franz Announces Gruff 8.1, Bringing Visual Knowledge Graphs to Web Pages and Web Apps

Franz Inc., a supplier of graph database technology, has announced Gruff 8.1, a knowledge graph visualization software tool that can be embedded in any web page or web application. Users can now visually build queries and visualize connections between enterprise data directly within a web page or web application, enabling a simple and seamless knowledge discovery experience.

“The ability to visualize data has become essential to every organization, in every industry,” said Dr. Jans Aasman, CEO of Franz Inc. “Gruff’s dynamic data visualizations enable a broad set of users to determine insights that would otherwise elude them by displaying data in a way that they can see the significance of the information relative to a business problem or solution. Gruff 8.1 makes it simple to weave these knowledge graph visualizations into web applications or web pages?further extending the power of the enterprise data fabric.”

Gruff, which is available as a browser-based application or pre-integrated into AllegroGraph, is a no-code visual query application that enables users to create visual knowledge graphs that display data relationships in views driven by the user. Gruff’s visual query builder empowers both novice and expert users to create simple to highly complex queries without writing any code. The unique “time machine” function within Gruff gives users the capability to explore temporal context and connections within data.

Gruff 8.1 can be embedded into any web page for use inside a web application or website. By embedding Gruff, developers can create applications that include graph visualization as part of the user interface. Visualizations can be customized to fit a specific user experience, data relationships or business requirements.

  • Developers can simply embed Gruff in an HTML iframe to allow a reader to use it inside a web page. The browser's standard commands can be used for zooming the entire application. An advanced feature also allows a web application to send custom commands to Gruff. For example, an application could derive a set of triples that it wants Gruff to display, and then send those triples to Gruff.
  • Special dialogs appear in Gruff 8.1 when saving or loading a SPARQL query, graphical query, or layout. The dialog shows descriptive information about each file and allows the user to filter the list of choices in various ways to make it easier to locate the desired file. Saved files will know which triplestore they work with and only those will be listed by default.
  • Users can now add comment nodes in the graphical query view of Gruff 8.1 to explain the entire query or particular parts of the query. Simply add a node that displays a comment somewhere inside the graphical query diagram, which has no effect on the textual query that gets generated. It is possible to add any number of comment nodes to a query and position them near the relevant parts of the diagram or describe the full query.

Gruff is fully integrated with AllegroGraph, Franz’s semantic knowledge graph solution, which leverages Gruff’s advanced graph visualizations and graphical query builder to reveal hidden connections in knowledge graph data. AllegroGraph, with FedShard, allows infinite data integration through a patented approach that unifies data and knowledge base silos into an entity-event knowledge graph solution that can support big data analytics. AllegroGraph utilizes unique federated sharding capabilities that drive 360-degree insights and enable complex reasoning across distributed knowledge graphs.
