WebGL2-powered, highly performant large-scale data visualization

Installation

npm install deck.gl

Using deck.gl

deck.gl offers an extensive catalog of pre-packaged visualization "layers", including ScatterplotLayer, ArcLayer, TextLayer, GeoJsonLayer, etc. The input to a layer is usually an array of JSON objects. Each layer offers a highly-flexible API to customize how the data should be rendered.

Example constructing a deck.gl ScatterplotLayer:

import {ScatterplotLayer} from '@deck.gl/layers';

/**
 * data is an array of object in the shape of:
 * {
 *   "name":"Montgomery St. (MONT)",
 *   "address":"598 Market Street, San Francisco CA 94104",
 *   "entries":"43430",
 *   "exits":"45128",
 *   "coordinates":[-122.401407,37.789256]
 * }
 */
const scatterplotLayer = new ScatterplotLayer({
  id: 'bart-stations',
  data: 'https://github.com/uber-common/deck.gl-data/blob/master/website/bart-stations.json',
  getRadius: d => Math.sqrt(d.entries) / 100,
  getPosition: d => d.coordinates,
  getFillColor: [255, 228, 0],
});

Using deck.gl with React

import DeckGL from 'deck.gl';

<DeckGL
  width="100%"
  height="100%"
  initialViewState={{longitude: -122.4, latitude: 37.78, zoom: 8}}
  controller={true}
  layers={[scatterplotLayer]} />

Using deck.gl with Pure JS

import {Deck} from '@deck.gl/core';

const deck = new Deck({
  width: '100vw',
  height: '100vh',
  initialViewState: {
    longitude: -122.4,
    latitude: 37.78,
    zoom: 8
  },
  controller: true,
  layers: [scatterplotLayer]
});

Minimum setups of end-to-end deck.gl usage is also showcased in the hello-world examples, using both webpack and browserify, so you can choose which bundler you prefer or are more familiar with.

To learn how to use deck.gl through the many examples that come with the deck.gl repo, please clone the latest release branch:

git clone -b 7.3-release --single-branch https://github.com/uber/deck.gl.git
