"reviver" is supposed to be a function (that you provide) that transforms
every key/value pair in the JSON into the final javascript object. It's
useful for converting date strings into Date objects and stuff like that,
but you probably don't have to worry about it. There is no JSON.eval
function - it is just eval. I would avoid using that, though.
I think I see the problem, though. You are missing the "new" keyword when
you declare the DataTable. It should be exactly like this:
var data = new google.visualization.DataTable(jsonData);
or, if that doesn't work, this:
var data = new google.visualization.DataTable(JSON.parse(jsonData));
Either way, the "new" keyword is critically important.
