Ontodia npm CircleCI

Ontodia is a JavaScript library that allows to visualize, navigate and explore data in the form of an interactive graph based on underlying data sources. The library is a major front-end component in ontodia.org web application that provides semantic data visualization services.

What is Ontodia for?

Ontodia allows you to create and persist diagrams made from existing data - relational, object, semantic.

It was designed to visualize RDF data sets in particular, but could be tailored to almost any data source by implementing a data provider interface.

Core features

  • Visual navigation and diagramming over large graph data sets
  • Rich graph visualization and context-aware navigation features
  • Ability to store and retrieve diagrams
  • User friendly - no graph query language or prior knowledge of the schema required
  • Customizable user interface (by modifying templates for nodes and links) and data storage back-end

How to try it?

You can:

  • Open ontodia.org demo diagram and navigate through demo data set
  • Create an account at ontodia.org, browse through sample diagrams, upload your RDF file or point to your SPARQL endpoint to build diagrams over your data
  • Follow developer tutorials at the developer documentation page

Please note that on Ontodia.org we deployed the commercial version of the Ontodia library, which includes some additional features:

  • Support of undo/redo for user actions
  • Multiple selection of nodes
  • Rectangular box multiple selection of nodes
  • Multiple removal of nodes from diagrams
  • Snap guides for node alignment
  • Additional layouts for better distribution of nodes on the canvas, etc.

How to use it

  • Use it as service at ontodia.org. Connect to your data, create and share diagrams
  • Customize it and embed into your web application as a JavaScript library
