The Nodium Core library contains all the basic functionality to start building awesome graph visualisations. The core functionality can be expanded by including the distributables from the nodium/neo4j and nodium/ui repositories.
Download the zip and include dist/nodium.min.js in your html.
The npm package is in the works.
See the nodium/nodium repository for example code.
