CSS

/* Always set the map height explicitly to define the size of the div
 * element that contains the map. */
#map {
  height: 425px;

/* Optional: Makes the sample page fill the window. */

  height: 100%;

JavaScript

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

  // Load GeoJSON.
  map.data.loadGeoJson(
      'https://geo.bergenheim.net/rivers.json');

  // Set the stroke width, and fill color for each polygon
  map.data.setStyle({
    strokeColor: 'pink',
    strokeWeight: 2
  });
}
