What is deck.gl?

deck.gl is a powerful WebGL-powered framework for visual exploratory data analysis of large datasets. It provides a suite of highly performant, customizable layers for rendering complex data visualizations on top of maps.

What are deck.gl's main functionalities?

ScatterplotLayer

The ScatterplotLayer is used to render scatter plot points on a map. Each point can be customized with different sizes and colors.

const {DeckGL, ScatterplotLayer} = require('deck.gl');

const scatterplotLayer = new ScatterplotLayer({
  id: 'scatterplot-layer',
  data: [
    {position: [-122.45, 37.78], size: 100},
    {position: [-122.46, 37.79], size: 200}
  ],
  getPosition: d => d.position,
  getRadius: d => d.size,
  getColor: [255, 0, 0]
});

const deckgl = new DeckGL({
  initialViewState: {
    longitude: -122.45,
    latitude: 37.78,
    zoom: 12
  },
  controller: true,
  layers: [scatterplotLayer]
});

GeoJsonLayer

The GeoJsonLayer is used to render GeoJSON data. It supports features like picking, extruding, and coloring of GeoJSON polygons.

const {DeckGL, GeoJsonLayer} = require('deck.gl');

const geoJsonLayer = new GeoJsonLayer({
  id: 'geojson-layer',
  data: 'https://raw.githubusercontent.com/uber-common/deck.gl-data/master/examples/geojson/vancouver-blocks.json',
  pickable: true,
  stroked: false,
  filled: true,
  extruded: true,
  getFillColor: [160, 160, 180, 200],
  getLineColor: [255, 255, 255],
  getRadius: 100,
  getLineWidth: 1
});

const deckgl = new DeckGL({
  initialViewState: {
    longitude: -123.1,
    latitude: 49.28,
    zoom: 11
  },
  controller: true,
  layers: [geoJsonLayer]
});

ArcLayer

The ArcLayer is used to render arcs between pairs of coordinates. It is useful for visualizing connections or flows between locations.

const {DeckGL, ArcLayer} = require('deck.gl');

const arcLayer = new ArcLayer({
  id: 'arc-layer',
  data: [
    {source: [-122.45, 37.78], target: [-122.46, 37.79]},
    {source: [-122.46, 37.79], target: [-122.47, 37.80]}
  ],
  getSourcePosition: d => d.source,
  getTargetPosition: d => d.target,
  getSourceColor: [0, 128, 200],
  getTargetColor: [255, 0, 0],
  getWidth: 2
});

const deckgl = new DeckGL({
  initialViewState: {
    longitude: -122.45,
    latitude: 37.78,
    zoom: 12
  },
  controller: true,
  layers: [arcLayer]
});
