3D Force-Directed Graph

A web component to represent a graph data structure in a 3-dimensional space using a force-directed iterative layout. Uses ThreeJS/WebGL for 3D rendering and either d3-force-3d or anvaka's ngraph for the underlying physics engine.

See also the VR version.

Quick start

import ForceGraph3D from '3d-force-graph';

or

var ForceGraph3D = require('3d-force-graph');

or even

<script src="//unpkg.com/3d-force-graph"></script>

then

var myGraph = ForceGraph3D();
myGraph(<myDOMElement>)
    .graphData(<myData>);

API reference

Method	Description	Default
width([px])	Getter/setter for the canvas width.	<window width>
height([px])	Getter/setter for the canvas height.	<window height>
graphData([data])	Getter/setter for graph data structure (see below for syntax details). Can also be used to apply incremental updates.	{ nodes: [], links: [] }
jsonUrl([url])	URL of JSON file to load graph data directly from, as an alternative to specifying graphData directly.
numDimensions([int])	Getter/setter for number of dimensions to run the force simulation on (1, 2 or 3).	3
nodeRelSize([num])	Getter/setter for the ratio of node sphere volume (cubic px) per value unit.	4
nodeResolution([num])	Getter/setter for the geometric resolution of each node, expressed in how many slice segments to divide the circumference. Higher values yield smoother spheres.	8
lineOpacity([num])	Getter/setter for line opacity of links, between [0,1].	0.2
autoColorBy([str or fn])	Node object accessor function (fn(node)) or attribute (e.g. 'type') to automatically group colors by. Only affects nodes without a color attribute.
idField([str])	Node object accessor attribute for unique node id (used in link objects source/target).	'id'
valField([num, str or fn])	Node object accessor function, attribute or a numeric constant for the node numeric value (affects sphere volume).	'val'
nameField([str or fn])	Node object accessor function or attribute for name (shown in label).	'name'
colorField([str or fn])	Node object accessor function or attribute for node color (affects sphere color).	'color'
onNodeClick(fn)	Callback function for node clicks. The node object is included as single argument onNodeClick(node).	-
linkSourceField([str])	Link object accessor attribute referring to id of source node.	'source'
linkTargetField([str])	Link object accessor attribute referring to id of target node.	'target'
forceEngine([str])	Getter/setter for which force-simulation engine to use (d3 or ngraph).	'd3'
warmupTicks([int])	Getter/setter for number of layout engine cycles to dry-run at ignition before starting to render.	0
cooldownTicks([int])	Getter/setter for how many build-in frames to render before stopping and freezing the layout engine.	Infinity
cooldownTime([num])	Getter/setter for how long (ms) to render for before stopping and freezing the layout engine.	15000
resetProps()	Reset all component properties to their default value.
