このスクリプトは、マーカーを追加し、それらの間にポリラインを描画します。
<script>
var poly;
var map;
function initialize() {
var chicago = new google.maps.LatLng(41.879535, -87.624333);
var mapOptions = {
zoom: 7,
center: chicago,
mapTypeId: google.maps.MapTypeId.ROADMAP

var polyOptions = {

strokeOpacity: 1.0,
strokeWeight: 3
}
poly = new google.maps.Polyline(polyOptions);
poly.setMap(map);
// Add a listener for the click event
google.maps.event.addListener(map, 'click', addLatLng);
}
/**
* Handles click events on a map, and adds a new point to the Polyline.
* @param {MouseEvent} mouseEvent
*/
function addLatLng(event) {
var path = poly.getPath();
// Because path is an MVCArray, we can simply append a new coordinate
// and it will automatically appear
path.push(event.latLng);
// Add a new marker at the new plotted point on the polyline.
var marker = new google.maps.Marker({
