Beautiful Graphs
♾ A Graph Visualization Framework in JavaScript.
Quick Overview
Force-Graph is a JavaScript library for creating interactive 2D and 3D force-directed graph visualizations. It leverages the d3-force physics engine to simulate the graph layout and provides a simple API for customizing node and link appearances, as well as handling user interactions.
Pros
- Easy to use API with minimal setup required
- Supports both 2D and 3D graph visualizations
- Highly customizable with numerous configuration options
- Smooth performance even with large datasets
Cons
- Limited built-in layout algorithms beyond force-directed
- Documentation could be more comprehensive for advanced use cases
- Dependency on Three.js for 3D rendering may increase bundle size
- Learning curve for complex customizations
Code Examples
Creating a basic 2D force graph:
const Graph = ForceGraph()
(document.getElementById('graph'))
.graphData(myData)
.nodeId('id')
.nodeLabel('name')
.linkSource('source')
.linkTarget('target');
Customizing node appearance:
const Graph = ForceGraph()
(document.getElementById('graph'))
.graphData(myData)
.nodeColor(node => node.group)
.nodeVal(node => node.size)
.nodeLabel(node => node.name);
Adding interactivity to the graph:
const Graph = ForceGraph()
(document.getElementById('graph'))
.graphData(myData)
.onNodeClick(node => {
// Center view on node
Graph.centerAt(node.x, node.y, 1000);
Graph.zoom(2, 1000);
});
Getting Started
-
Install the library:
npm install force-graph
-
Import and use in your project:
import ForceGraph from 'force-graph'; const myData = { nodes: [{ id: 'node1' }, { id: 'node2' }], links: [{ source: 'node1', target: 'node2' }] }; const Graph = ForceGraph() (document.getElementById('graph')) .graphData(myData);
-
Customize as needed using the available API methods.
Competitor Comparisons
Force-directed graph layout using velocity Verlet integration.
Pros of d3-force
- More flexible and customizable, allowing for fine-grained control over force simulations
- Part of the larger D3.js ecosystem, integrating seamlessly with other D3 modules
- Lightweight and focused solely on force simulation calculations
Cons of d3-force
- Steeper learning curve, requiring more in-depth knowledge of D3.js
- Requires additional code to render visualizations, as it only handles force calculations
- Less out-of-the-box functionality for graph visualization
Code Comparison
d3-force:
const simulation = d3.forceSimulation(nodes)
.force("link", d3.forceLink(links).id(d => d.id))
.force("charge", d3.forceManyBody())
.force("center", d3.forceCenter(width / 2, height / 2));
force-graph:
const Graph = ForceGraph()
(document.getElementById('graph'))
.graphData(data)
.nodeId('id')
.nodeVal('val')
.linkSource('source')
.linkTarget('target');
Summary
d3-force provides more flexibility and integration with D3.js but requires more setup and coding. force-graph offers a higher-level API with more built-in features for graph visualization, making it easier to use out of the box. The choice between them depends on the specific requirements of the project and the developer's familiarity with D3.js.

Beautiful Graphs
Pros of ngraph
- More flexible and modular architecture, allowing for custom physics engines and renderers
- Better performance for large-scale graphs with thousands of nodes
- Supports both 2D and 3D graph layouts out of the box
Cons of ngraph
- Steeper learning curve due to its modular nature
- Less built-in interactivity features compared to force-graph
- Requires more setup and configuration for basic use cases
Code Comparison
force-graph:
const Graph = ForceGraph()
.graphData(data)
.nodeId('id')
.nodeVal('val')
.nodeLabel('name')
.linkSource('source')
.linkTarget('target');
ngraph:
const graph = createGraph();
data.nodes.forEach(node => graph.addNode(node.id));
data.links.forEach(link => graph.addLink(link.source, link.target));
const layout = createLayout(graph);
const renderer = createRenderer(graph, layout);
Both force-graph and ngraph are powerful graph visualization libraries, but they cater to different use cases. force-graph offers a more straightforward API with built-in interactivity, making it ideal for quick prototyping and simpler graph visualizations. ngraph, on the other hand, provides greater flexibility and performance for complex, large-scale graph scenarios, but requires more setup and customization. The choice between the two depends on the specific requirements of your project, such as graph size, performance needs, and desired level of customization.

Render control
Method | Description | Default |
---|---|---|
autoPauseRedraw([boolean]) | Getter/setter for performance optimization to automatically pause redrawing the canvas at every frame whenever the simulation engine is halted. If you have custom dynamic objects that rely on a constant redraw of the canvas, it's recommended to switch this option off. | true |

centerAt([x], [y], [ms]) | Getter/setter for the coordinates of the center of the viewport. This method can be used to perform panning on the canvas programmatically. Each of the x, y coordinates is optional, allowing for motion in just one dimension. An optional 3rd argument defines the duration of the transition (in ms) to animate the canvas motion. A value of 0 (default) centers immediately in the final position. | 0,0 |
zoom([num], [ms]) | Getter/setter for the canvas zoom amount. The zoom is defined in terms of the scale transform of each px. A value of 1 indicates unity, larger values zoom in and smaller values zoom out. An optional 2nd argument defines the duration of the transition (in ms) to animate the canvas motion. A value of 0 (default) jumps immediately to the final position. | By default the zoom is set to a value inversely proportional to the amount of nodes in the system. |
zoomToFit([ms], [px], [nodeFilterFn]) | Automatically zooms/pans the canvas so that all of the nodes fit inside it. If no nodes are found no action is taken. It accepts three optional arguments: the first defines the duration of the transition (in ms) to animate the canvas motion (default: 0ms). The second argument is the amount of padding (in px) between the edge of the canvas and the outermost node (default: 10px). The third argument specifies a custom node filter: node => <boolean> , which should return a truthy value if the node is to be included. This can be useful for focusing on a portion of the graph. | (0, 10, node => true) |
minZoom([num]) | Getter/setter for the lowest zoom out level permitted. | 0.01 |
maxZoom([num]) | Getter/setter for the highest zoom in level permitted. | 1000 |
onRenderFramePre(fn) | Callback function to invoke at every frame, immediately before any node/link is rendered to the canvas. This can be used to draw additional external items on the canvas. The canvas context and the current global scale are included as parameters: .onRenderFramePre(<canvas context>, <global scale>) . | - |
onRenderFramePost(fn) | Callback function to invoke at every frame, immediately after the last node/link is rendered to the canvas. This can be used to draw additional external items on the canvas. The canvas context and the current global scale are included as parameters: .onRenderFramePost(<canvas context>, <global scale>) . | - |

dagLevelDistance([num]) | If dagMode is engaged, this specifies the distance between the different graph depths. | auto-derived from the number of nodes |
dagNodeFilter([fn]) | Node accessor function to specify nodes to ignore during the DAG layout processing. This accessor method receives a node object and should return a boolean value indicating whether the node is to be included. Excluded nodes will be left unconstrained and free to move in any direction. | node => true |
onDagError([fn]) | Callback to invoke if a cycle is encountered while processing the data structure for a DAG layout. The loop segment of the graph is included for information, as an array of node ids. By default an exception will be thrown whenever a loop is encountered. You can override this method to handle this case externally and allow the graph to continue the DAG processing. Strict graph directionality is not guaranteed if a loop is encountered and the result is a best effort to establish a hierarchy. | throws exception |
d3AlphaMin([num]) | Getter/setter for the simulation alpha min parameter. | 0 |
d3AlphaDecay([num]) | Getter/setter for the simulation intensity decay parameter. | 0.0228 |
