Use the TopoJSON

Import

// Use a country's ISO alpha 2 code
// Germany
import topology from '@reuters-graphics/graphics-atlas-client/topojson/DE.json';

// Use a UN region or sub-region's slug to get a collection of countries
// Africa
import topology from '@reuters-graphics/graphics-atlas-client/topojson/africa.json';
// Central America
import topology from '@reuters-graphics/graphics-atlas-client/topojson/central-america.json';

// World includes all countries and disputed boundaries
import topology from '@reuters-graphics/graphics-atlas-client/topojson/world.json';

Fetch from client

import AtlasMetadataClient from '@reuters-graphics/graphics-atlas-client';

const client = new AtlasMetadataClient();

// Use a country's name, slug or ISO code
client.fetchCountryTopojson('germany')
  .then((topojson) => { ... });

// Use a UN region or sub-region's name or slug to get a collection of countries
client.fetchRegionTopojson('Africa')
  .then((topojson) => { ... });

// Get the world topojson
client.fetchGlobalTopojson()
  .then((topojson) => { ... });

Fetch from CDN

fetch('https://cdn.jsdelivr.net/npm/@reuters-graphics/graphics-atlas-client@latest/topojson/world.json')
  .then(res => res.json())
  .then((topology) => {
    console.log(topology);
  });

Building data

$ yarn build:metadata
$ yarn build
$ yarn build:maps
$ yarn build:maps:custom

Centroids

Centroids for each country are automatically calculated and added to the properties of each country's topojson. You can override the default calculation by adding a custom centroid to the data/custom_centroids.csv file and rebuilding the maps.
