พี่ค่ะ ถามเรื่องการสร้างกราฟจาก google ค่ะ ทำไมกราฟไม่ขึ้นค่ะ

<?php

$objConnect = mysql_connect("localhost","root","1234") or die(mysql_error());
$objDB = mysql_select_db("mydatabase");
$strSQL = "SELECT * FROM customer";
$objQuery = mysql_query($strSQL) or die (mysql_error());
$resultArray = array();

?>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);
        
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Year', 'square'],
          <?php
		  while($obResult = mysql_fetch_array($objQuery))
			{
				array_push($resultArray,$obResult);
				//echo $obResult['Name'];
				 echo "['".$obResult['Name']."',".$obResult['Budget']."],";
				
			}

          ?>
        ]);

        var options = {            
          title: 'Model',
          vAxis: {title: "square metre"},
          width: data.getNumberOfRows() * 65,
          bar: {groupWidth: 35},
          tooltip: {textStyle: {color: '#3C6A9D'}, showColorCode: true},
          chartArea : {left:80,top:60,width:"80%", height: "60%"}
          
        };
              
            
        var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
 <div class="chart_div " id="chart_div"></div>
