<script type="text/javascript"> 
google.load('visualization', '1', {'packages':['corechart']}); 
google.setOnLoadCallback(drawChart);  
function drawChart()
{
    var data = new google.visualization.DataTable(); 
    data.addColumn('string', 'Name'); 
    data.addColumn('number', 'Count'); 

    data.addRows([ ['Value A',5 ],['Value B',61 ],['Value C',53 ],['Value D',22 ] ]); 
    var chart = new google.visualization.PieChart(document.getElementById('chart_div')); 
    chart.draw(data, {width: 400, height: 280, is3D: true, title: ''});

    google.visualization.events.addListener(chart, 'select', selectHandler); 

    function selectHandler(e)     {   
        alert(data.getValue(chart.getSelection()[0].row, 0));
    }

}
