Create a JavaScript function to display the map:

Example

function myMap() {
    var mapCanvas = document.getElementById("map");
    var mapOptions = {
        center: new google.maps.LatLng(51.5, -0.2),
        zoom: 10
    };
    var map = new google.maps.Map(mapCanvas, mapOptions);
}

The mapCanvas variable is the map's HTML element.

The mapOptions variable defines the properties for the map.

The center property specifies where to center the map (using latitude and longitude coordinates).

The zoom property specifies the zoom level for the map (try to experiment with the zoom level).

The google.maps.Map object is created with mapCanvas and mapOptions as parameters.


Add the Google API

The functionality of the map is provided by a JavaScript library located at Google:

Example

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_KEY&callback=myMap"></script>
