Google Charts: How to pass a JSON data to ChartWrapper() function?

[abhishek sinha]

In the example given in the documentation (link:https://developers.google.com/chart/interactive/docs/reference#example_7), how to send data in the form of JSON instead of URL?? 

CODE:

var wrapper = new google.visualization.ChartWrapper({
         'chartType':'LineChart',
         'dataSourceUrl':'http://spreadsheets.google.com/tq?key=pCQbetd-CptGXxxQIG7VFIQ&pub=1',
         'query':'SELECT A,D WHERE D > 100 ORDER BY D',
         'options': {'title':'Population Density (people/km^2)', 'legend':'none'}
      });

In the above code, instead of passing data through URL by dataSourceUrl, I want to send data by JSON. What parameter should I use instead of dataSourceUrl?
