Answer 1

1) try this:

$wnd.google.load("visualization", "1.0", {packages : [ 'corechart' ], callback: drawVisualization});

instead of these 2 lines:

$wnd.google.load('visualization', '1', {packages: ['corechart']});


$wnd.google.setOnLoadCallback(drawVisualization);

or 2) call google.load in your HTML page with
