Well, Simply failed to understand why it does not work Google Maps.
I read almost all the documentation, not only for the problems I have, but it also because I needed to use polygons, among others.

**So, this is my code(*I put some comments so that they can understand more quickly*):**

```
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<div style="width:100%;height:400px;padding:0;margin:0;">
    <div id="canvas" style="width:100%; height:100%;padding:0;margin:0;"></div>
</div>

<script>
    function initialize() {
        var colors = ['#00bfff','#7eabe9','#799fe7','#7293e5','#6989e4','#5e7ee3','#5273e2','#4169e1','#4b6fde','#5274db','#5979d8','#5f7fd5','#6584d2','#698acf','#1e90ff'];
        var location = [
            {"name":"lisboa","lat":38.725717,"lng":-9.150248},
            {"name":"madrid","lat":40.420275,"lng":-3.705766},
            {"name":"burdeos","lat":44.836625,"lng":-0.581048},
            {"name":"loira","lat":46.621773,"lng":2.452032},
            {"name":"paris","lat":48.856929,"lng":2.341198},
            {"name":"bruselas","lat":50.848375,"lng":4.349679},
            {"name":"rotterdam","lat":51.922848,"lng":4.478452},
            {"name":"amsterdam","lat":52.373085,"lng":4.893276}
        ];
        var map = new google.maps.Map(document.getElementById('canvas'), {
            'center'    :   new google.maps.LatLng(0,-180),
            'zoom'      :   3,
            'mapTypeId' :   google.maps.MapTypeId.TERRAIN
        });

        // store positions on var flightPlanCoordinates
        var flightPlanCoordinates = [];

        // set markers and popovers/infWindow
        // *remember var flightPlanCoordinates*
        for (var i = 0; i < location.length; i++) {
            var lat     =   location[i].lat,
                lng     =   location[i].lng,
                name    =   location[i].name;
            var pos     =   new google.maps.LatLng(lat, lng);
            var infowindow =  new google.maps.InfoWindow({
                'content'   :   name,
                'map'       :   map,
                'position'  :   pos
            });
            infowindow.close();
            flightPlanCoordinates.push(pos);
            var marker = new google.maps.Marker({
                'position'  :   pos,
                'map'       :   map,
                'title'     :   name,
                'icon'      :   {
                    'path'      :   google.maps.SymbolPath.CIRCLE,
                    'scale'     :   5,
                    'strokeColor':  colors[i]
                }
            });
            google.maps.event.addListener(marker, 'click', function() {
                if (infowindow) {
                    infowindow.close();
                }
                infowindow.open(map, this);
            });
        }
        // set polylines
        // *remember var flightPlanCoordinates*
        for (var i = 0; i < flightPlanCoordinates.length; i++) {
            if(typeof flightPlanCoordinates[i+1] == 'undefined'){
                continue;
            }
            var PathStyle = new google.maps.Polyline({
                'path'          : [
                    flightPlanCoordinates[i],
                    flightPlanCoordinates[i+1]
                ],
                'strokeColor'   : colors[i],
                'strokeOpacity' : 1.0,
                'strokeWeight'  : 2,
                'map'           : map
            });
        }
    }
    // Draw Google Maps V3
    google.maps.event.addDomListener(window, 'load', initialize);
</script>
