object inside object javascript google table

I'm trying to use Google's chart: http://ift.tt/1ppbI5g

I have some objects inside another object that I want to insert into the table. My question is this: do I have to put them into an array?

My code so far:

How do I get the objects from a JSON file:

function getTotalBundles() {
    var totalBundles = {};
    for (var i = 0, max = users.length; i < max; i++) {
        var user = users[i];
        for (var bundle in user.bundles) {
            if (user.bundles.hasOwnProperty(bundle)) {
                if (!totalBundles[bundle])
                    totalBundles[bundle] = 0;

                ++totalBundles[bundle];
            }
        }
    }
    return totalBundles;
}

function drawTable() {
    var data = new google.visualization.DataTable();
    var temp = getTotalBundles();

    data.addColumn('string', 'Name');
    data.addColumn('number', 'Purchased');
    data.addRows(....);
}
