Google Map API:
- We declare the application as HTML5 using the declaration.
- We include the Maps API JavaScript using a script tag.
- We create a div element named "map-canvas" to hold the Map.
- We create a JavaScript object literal to hold a number of map properties.
- We create a JavaScript "map" object, passing it the div element and the map properties.
- We use an event listener to load the map after the page has loaded.
