Javascript

This example passes in a JSON string representation of the chart, which you might have loaded from a file:

<script type="text/javascript>
  google.load('visualization',' 1.0');
  var myStoredString = '{"containerId": "visualization_div",'; +
        '"dataSourceUrl:": "https://spreadsheets.google.com/a/google.com/tq?key=pCQbetd-CptGXxxQIG7VFIQ&pub=1",' +
        '"query":"SELECT A,D WHERE D > 100 ORDER BY D" ,' +
        '"refreshInterval": 5,' +
        '"chartType": "Pie",' +
        '"options":{'+
        '  "alternatingRowStyle": true,' +
        '   "showRowNumber" : true' +
        '}' +
      '}';
  function drawVisualization() {
    google.visualization.drawChart(myStoredString);
  }
  google.setOnLoadCallback(drawVisualization);
</script>

I have a query with multiple aggregate function which must get replaced in "query",but I'm unable to refer the query. Please guide me.
Or if there is any other alternative,please suggest.
My requirement is to display a 2D pie chart where I can connect to my datasource and stored procedure/query.
