You can put the data in one string and use JSON.parse(stringData). The year column must be in double quotes

var data = new google.visualization.DataTable();  
data.addColumn('string', 'Year');  
data.addColumn('number', 'Sales'); 
data.addColumn('number', 'Expenses'); 

var stringData = '[["2004", 1000 , 400], ["2005", 1170, 460], ["2006", 660, 1120], ["2007",1030,540]]';

data.addRows(JSON.parse(stringData));
