Google Maps API v3 Highlight Country Border without using Polygons

Question

I need to highlight the border of a country - let's say Switzerland. I achieved it with already with FusionTablesLayer like:

        var layer = new google.maps.FusionTablesLayer({
                    query: {
                        select: 'geometry',
                        from: '1N2LBk4JHwWpOY4d9fobIn27lfnZ5MDy-NoqqRpk',
                        where: "ISO_2DIGIT IN ('CH')"
                    },
                    styles: [
                        {
                            polygonOptions: {
                                strokeColor: "#FF0000",
                                fillOpacity: "0"
                            }
                        }
                    ]
                });

                layer.setMap(map);

The problem hereby is, that the drawn border is too straight

Is there any possibility to use some kind of search request, because if I go to Google Maps and search for Switzerland the country borders are highlighted in a light pink. This would already fullfil my requirements. See Maps

Thanks in advance
