我在使用谷歌图表时遇到问题，但没有任何显示。当我删除 php 代码时，它说没有数据，但是代码却没有出现。这是代码：

   <?php
    $con = mysqli_connect('localhost', 'root', '');
    mysqli_select_db($con, 'gamefort');

    $s = " select naziv, broj from konzola group by naziv ";
    $result = mysqli_query($con, $s);
    ?>

<script type="text/javascript">
        google.charts.load('current', {
            'packages': ['corechart']
        });
        google.charts.setOnLoadCallback(drawChart);

        function drawChart() {
            var data = new google.visualization.arrayToDataTable([
                ['Naziv','Broj'],
                <?php
                while($row = mysqli_fetch_assoc($result)){
                    echo "['".$row["naziv"].",".$row["broj"]."'],";
                }
                ?>
            ]);

            var options = {
                'title': 'Statistika',
                'width': 400,
                'height': 300
            };

            var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
            chart.draw(data, options);
        }
</script>

有什么建议？提前致谢。
