I would like to be able to hide/show each line in a diagram by clicking on 
the name for that line in the legend. I am familiar with the solution 
provided here:
http://jsfiddle.net/asgallant/WaUu2/ 
but is there any way to do what I am trying to achieve (ie. using the 
legend options to turn on/off the different lines in the diagram)?

google.load('visualization', '1', {packages:['corechart']});
google.setOnLoadCallback(drawTable);
function drawTable() {
    var data = new google.visualization.DataTable();

    data.addColumn('string', 'Organisation');        
    data.addColumn('number', 'Finland');                    
    data.addColumn('number', 'Germany');                    
    data.addColumn('number', 'Sweden');    
                   
    data.addRows([
    
['2010',655.68,650.48,4290.84],['2011',680.57,606.07,3743.17],['2012',931.97,402,402.99]]);

    var options = {
    chartArea:{left:80,top:50}
    };

    var table = new 
google.visualization.LineChart(document.getElementById('column'));
    table.draw(data, options);
}
