I try to write you some pseudocode.. Try to do something like this.
For the first, create new class Result for example.. There will be your rows from database in one array..


Class Result
{
  private $rowName;
  private $rowValue;

  _construct Result()
  {
    $this->rowName="";
    $this->rowValue="";
  }

  /*
  getters and setters will be here
  */
}


$query = "SELECT name FROM mybase WHERE name = '$name' ";
 

        $mysqli = new mysqli();
        $mysqli->connect('localhost', 'blabla', 'blabla', 'blabla');
        $result = $mysqli->query($query);
        
        $arrayResult = array();
        while ($row = $result->fetch_assoc()) {
           $arrayResult[] = $row['rowName'];  //rows will be added into array
        }
 

<html>
  <head>
    <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([
          ['Name', 'Seen x times'],
<?php
foreach($arrayResult as $graphValue)
{
  echo "['".$graphValue.getRowName()."'], ".$grapghValue.getRowValue()." ],"...
  //here you should check if next row is the last and then -> , not will be there..
}
? >
        ]);
 
        var options = {
          title: 'My Daily Activities'
        };
 
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
  </head>
  <body>
    <div id="chart_div" style="width: 900px; height: 500px;"></div>
  </body>
</html>
