I have rewritten your code using Rest API and creating object which can be directly fed to the google.visualization.arrayToDataTable. Exclusion of external reference and reduction of If would help you decrease the load time.

Also below code help you remove hard coding of status which would help you on longer run.

<div id="piechart" style="width:900px;height:500px;"></div>
<script src="https://www.gstatic.com/charts/loader.js" type="text/javaScript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js" type="text/javaScript"></script>
<script type="text/javaScript">
     $(document).ready(function() {
       var tempArray = [];
       var chartObj = [['status', 'Number']];

AjaxCall(_spPageContextInfo.webAbsoluteUrl + "/_api/Web/Lists/GetByTitle('Certify1')/Items?$select=Status_x0020_as_x0020_on_x0020_d", function(data) {
    $.each(data.d.results, function(index, value) {
        if (0 > tempArray.indexOf(value["Status_x0020_as_x0020_on_x0020_d"])) {
            tempArray.push(value["Status_x0020_as_x0020_on_x0020_d"]);
            chartObj.push([value["Status_x0020_as_x0020_on_x0020_d"], 1])
        } else {
            chartObj[tempArray.indexOf(value["Status_x0020_as_x0020_on_x0020_d"]) + 1][1] += 1;
        }
    });
    google.charts.load('current', {
        'packages': ['corechart']
    });
    google.charts.setOnLoadCallback(function() {
        var data = google.visualization.arrayToDataTable(chartObj);
        var options = {
            title: 'Certification Report Status',
            is3D: 'true'
        };
        var chart = new google.visualization.PieChart(document.getElementById('piechart'));
        chart.draw(data, options);
    });
});
});
function AjaxCall(url, success) {
$.ajax({
    url: url,
    type: "GET",
    headers: {
        "accept": "application/json;odata=verbose",
    },
    success: success,
    error: function(error) {
        console.log(JSON.stringify(error));
        alert('Something Went Wrong');
    }
});
}
</script>

I have run this code and it is working for me. If issue persists check for the following things:

1. Column Name
2. List Name
3. Browser Compatibiliity
4. Items in the List

Hope this solves your issue.
