Hello Everyone,

So I came up from the simple line chart example and develop the code into this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>Google Visualization API Sample</title>
<!--
  One script tag loads all the required libraries! Do not specify any chart types in the
  autoload statement.
-->
<script type="text/javascript"
      src='https://www.google.com/jsapi?autoload={
        "modules":[{
        "name":"visualization",
        "version":"1"
        }]
      }'></script>
<script type="text/javascript">
  google.setOnLoadCallback(drawVisualization);

  function drawVisualization() {
    var wrap = new google.visualization.ChartWrapper({
       'chartType':'LineChart',
       'dataSourceUrl':'http://amr2.mybluemix.net/getmet/list',
       'containerId':'visualization',
       'query':'SELECT currA,timetag',
       'options': {'title':'Example Chart', 'legend':'none'}
       });
     wrap.draw();
  }
</script>
</head>
<body>
  <div id="visualization" style="height: 400px; width: 400px;"></div>
</body>
</html>



My code doesn't work. Anybody can show me what I have been missing?
