That is a typo error. Use

var wrapper = new google.visualization.ChartWrapper({
                    chartType: 'ColumnChart',
                    dataTable: [['',Name[0], Name[1],Name[3]],
                  ['', 700, 300, 400]],
                    options: { 'title': 'Countries' },
                    containerId: 'visualization'
                });

and try this format to prevent mistakes:

var data = google.visualization.arrayToDataTable([
          [title, 'countries'],
          [Name[0],  1000],
          [Name[1],  1170],
        ]);
