This example uses a data layer to set the stroke width and fill color for the samples provided from a GeoJSON file.

Read the documentation.

TypeScript

let map: google.maps.Map;

function initMap(): void {
  map = new google.maps.Map(document.getElementById("map") as HTMLElement, {
    zoom: 4,
    center: { lat: -28, lng: 137 }
  });

  // NOTE: This uses cross-domain XHR, and may not work on older browsers.
  map.data.loadGeoJson(
    "https://storage.googleapis.com/mapsdevsite/json/google.json"
  );
}

JavaScript

let map;

function initMap() {
  map = new google.maps.Map(document.getElementById("map"), {
    zoom: 4,
    center: { lat: -28, lng: 137 }
  });
  // NOTE: This uses cross-domain XHR, and may not work on older browsers.
  map.data.loadGeoJson(
    "https://storage.googleapis.com/mapsdevsite/json/google.json"
  );
