Neo4j Visualization Library

Welcome to NVL (Neo4j Visualization Library). NVL is a collection of libraries that can be used to build custom graph visualizations like Neo4j Bloom. The NVL library is also available as a React component that can be used in React applications.

This module is a collection of decorator classes that can be used to add interaction events to an NVL instance. The decorators are applied to the NVL class. You can find more information about the NVL class in the base library documentation.

Consuming the library

Installing the library

You can install the interaction handlers with your preferred package manager, for example

npm install @neo4j-nvl/interaction-handlers

If you are planning to use NVL in a React app, be sure to check out the NVL React wrappers.

Using the library

Heres is an example on how to use an interaction handler with the NVL class:

import { ClickInteraction } from '@neo4j-nvl/interaction-handlers'
import { NVL } from '@neo4j-nvl/base'
 *
const nvl = new NVL(nodes, relationships, options)
const clickInteraction = new ClickInteraction(nvl)
clickInteraction.updateCallback('onNodeClick', (node) => {
  console.log('Node clicked', node)
})

If you are using React and want to add interactivity to your graph, you can also make use of the InteractiveReactWrapper.

You can find more instructions and examples on how to use NVL interaction handlers in the docs.
