Ontodia

Ontodia is a JavaScript library that allows to visualize, navigate and explore the 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 is a JavaScript library that allows you to create and persist diagrams made from data - relational, object, semantic.

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

How do I get set up?

You can get Ontodia by using either npm or yarn:

$ npm install --save ontodia

$ yarn add ontodia

To quickly get Ontodia up and running run:

$ npm install && npm run demo

This will compile everything and you can start trying it.

http://localhost:10444/ will display Ontodia with static build-in data.
http://localhost:10444/sparql.html will display Ontodia with SPARQL endpoint set in SPARQL_ENDPOINT environment variable.

Usage of TypeScript

Ontodia library heavily uses TypeScript language. All type definitions are exported along with a library. It's not required to use TypeScript to use this library, but even for JS developers it's worth through TypeScript sources or ontodia.d.ts build output file to know API.

Usage of library in you own code

Ontodia interface is React-based application and you should initialize React component to work with. You can see example of initializing library in src/examples/template.ejs and src/examples/demo.ts.
