Read the documentation.

TypeScript

// This example creates a simple polygon representing the Bermuda Triangle.  function initMap(): void {   const map = new google.maps.Map(     document.getElementById("map") as HTMLElement,     {       zoom: 5,       center: { lat: 24.886, lng: -70.268 },       mapTypeId: "terrain",     }   );    // Define the LatLng coordinates for the polygon's path.   const triangleCoords = [     { lat: 25.774, lng: -80.19 },     { lat: 18.466, lng: -66.118 },     { lat: 32.321, lng: -64.757 },     { lat: 25.774, lng: -80.19 },   ];    // Construct the polygon.   const bermudaTriangle = new google.maps.Polygon({     paths: triangleCoords,     strokeColor: "#FF0000",     strokeOpacity: 0.8,     strokeWeight: 2,     fillColor: "#FF0000",     fillOpacity: 0.35,   });    bermudaTriangle.setMap(map); }

JavaScript

CSS

/* Always set the map height explicitly to define the size of the div        * element that contains the map. */ #map {   height: 100%; }  /* Optional: Makes the sample page fill the window. */ html, body {   height: 100%;   margin: 0;   padding: 0; }
