async function initMap() {
  // Request needed libraries.
  const { Map, InfoWindow } = await google.maps.importLibrary("maps");
  const { AdvancedMarkerElement, PinElement } = await google.maps.importLibrary(
    "marker",
  );

    zoom: 3,
    center: { lat: -28.024, lng: 140.887 },
    mapId: "DEMO_MAP_ID",
  });
  const infoWindow = new google.maps.InfoWindow({
    content: "",
    disableAutoPan: true,
  });
  // Create an array of alphabetical characters used to label the markers.
  const labels = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
  // Add some markers to the map.
  const markers = locations.map((position, i) => {
    const label = labels[i % labels.length];
    const pinGlyph = new google.maps.marker.PinElement({
      glyph: label,
      glyphColor: "white",
    });
    const marker = new google.maps.marker.AdvancedMarkerElement({
      position,
      content: pinGlyph.element,
    });

    // markers can only be keyboard focusable when they have click listeners
    // open info window when marker is clicked
    marker.addListener("click", () => {
      infoWindow.setContent(position.lat + ", " + position.lng);
      infoWindow.open(map, marker);
    });
    return marker;
  });

  // Add a marker clusterer to manage the markers.
  new MarkerClusterer({ markers, map });
