This is a fork of the following package: https://github.com/eisman/neo4jd3.
Neo4j graph visualization using D3.js.
Features
- Compaptible with the Neo4j data format and the D3.js data format.
- Force simulation.
- Info panel that shows nodes and relationships information on hover.
- Double click callbacks.
- Custom node colors by node type.
- Text nodes + Font Awesome icon nodes + SVG image nodes (e.g. using Twitter Emoji)).
- Sticky nodes (drag to stick, single click to unstick).
- Dynamic graph update (e.g. double click a node to expand it).
- Highlight nodes on init.
- Relationship auto-orientation.
- Zoom, pan, auto fit.
- Compatible with D3.js v4.

JavaScript API
| Function | Description |
| ----------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| appendRandomDataToNode(d, maxNodesToGenerate) | Generates between 1 and maxNodesToGenerate random nodes connected to node d and updates the graph data. |
| neo4jDataToD3Data(data) | Converts data from Neo4j data format to D3.js data format. |
| randomD3Data(d, maxNodesToGenerate) | Generates between 1 and maxNodesToGenerate random nodes connected to node d. |
| size() | Returns the number of nodes and relationships.Example:{ nodes: 25, relationships: 50} |
| updateWithD3Data(d3Data) | Updates the graph data using the D3.js data format. |
| updateWithNeo4jData(neo4jData) | Updates the graph data using the Neo4j data format. |
| version() | Returns the version of neo4jd3.js.Example: '0.0.1' |
