It looks like you are trying to do something like you might with a template
language. Javascript by itself doesn't work that way, however. You'll
need to do something like this instead:
var dataArray = ['Age', 'Weight'];
for(var i=0;i<arr1.length;i++) {
dataArray.push( [eval(arr1[i]),eval(arr2[i])] );
}
var data = google.visualization.arrayToDataTable(dataArray);
