@antv/layout-gpu

Accelerate some parallelizable algorithms such as Fruchterman with WebGPU which has a better performance under large amount of data.

Usage

NPM

# npm
$ npm install @antv/layout-gpu --save

# yarn
$ yarn add @antv/layout-gpu

Choose a layout algorithm from @antv/layout-gpu then.

import { Graph } from "@antv/graphlib";
import { FruchtermanLayout } from "@antv/layout-gpu";

const graph = new Graph({ nodes: [], edges: [] });

const fruchtermanLayout = new FruchtermanLayout();

(async () => {
  // Return positions of nodes & edges.
  const positions = await fruchtermanLayout.execute(graph);
  // Or to directly assign the positions to the nodes:
  await circularLayout.assign(graph);
})();

UMD

Import scripts in UMD version of @antv/graphlib, @antv/layout and @antv/layout-gpu.

<script
  src="https://unpkg.com/@antv/graphlib"
  type="application/javascript"
></script>
<script
  src="https://unpkg.com/@antv/layout"
  type="application/javascript"
></script>
<script
  src="https://unpkg.com/@antv/layout-gpu"
  type="application/javascript"
></script>

Use layouts under LayoutGPU namespace.

const { Graph } = window.GraphLib;
const { FruchtermanLayout } = window.LayoutGPU;

Documentation

We provide the following parallelizable layouts:

• Fruchterman
• GForce

import { Graph } from "@antv/graphlib";
import { FruchtermanLayout } from "@antv/layout-gpu";

const graph = new Graph({ nodes: [], edges: [] });

const fruchtermanLayout = new FruchtermanLayout({
  center: [200, 200],
});
const positions = await fruchtermanLayout.execute(graph);

Fruchterman

Fruchterman is a kind of force-directed layout. The implementation is according to the paper Graph Drawing by Force-directed Placement.

Online Demo

LayoutOptions:

• center [number, number] The center of the graph. e.g. [0, 0]
• width number The width of the graph. The default value is 300.
• height number The height of the graph. The default value is 300.
• maxIteration number The default value is 1000.
• gravity number The gravity, which will affect the compactness of the layout. The default value is 10.
• speed number The moving speed of each iteraction. Large value of the speed might lead to violent swing. The default value is 5.
