How to return a Date value from JSON to Google Visualization API

Question

is there a way to retrieve date value from JSON in Google Visualization API? Here is the snipplet for playground please copy the code below into it

When you run the code you won't have anything in result. you should remove the quotes from the date value I marked with comment in order to retrieve result.

function drawVisualization() {
var JSONObject = {
cols:
    [
        {id: 'header1', label: 'Header1', type: 'string'},
        {id: 'header2', label: 'Header2', type: 'date'}
    ],
rows: 
    [
        {
            c:
                [
                    {v: 'Value1'}, 
                    {v: "new Date(2010, 3, 28")}  // <= This is the format I receive from WebService
                ]
        },
        {
            c:
                [
                    {v: 'Value2'},
                    {v: new Date(2010, 3, 28)} // <=This is the format Google API accepts
                ]
        }
    ]
};

var data = new google.visualization.DataTable(JSONObject, 0.5);

visualization = new google.visualization.Table(document.getElementById('table'));
visualization.draw(data, {'allowHtml': true});
}
