  var data = google.visualization.arrayToDataTable([
    ['Year', 'Austria', 'Bulgaria' ],
    [12,  133,    400],
    [21,  153,    366],
    [20,  155,    240],

  new google.visualization.ColumnChart(document.getElementById('visualization')).
      draw(data,
           {title:"Yearly Coffee Consumption by Country",
            width:600, height:400,
            vAxis: {title: "Year",ticks: [{v:100, f:"100$"},{v:150, f:"150$"},{v:200, f:"200$"},{v:300, f:"300$"}]},
            hAxis: {title: "Cups",ticks: [{v:4, f:"3-4"},{v:8, f:"5-9"},{v:10, f:"9-13"},{v:14, f:"13-14"},{v:20, f:"15-20"}]} }
