Here is my database snap:

Here is my code:
<?php
$db=mysqli_connect("localhost","root","","organisation"); //db connection
$query=mysqli_query($db, "SELECT name,below_whom FROM org"); //fetch data
if($query){
$data=[];
while($org_data=mysqli_fetch_assoc($query)){
$data []= [$org_data["name"],$org_data["below_whom"]]; //syntax of
associative array = $variable["value"]
}
#echo '<pre>'; print_r($data); echo '</pre>';
}
else {
"Error".mysqli_error();
}
?>

var data = new google.visualization.DataTable();
data.addColumn('string', 'name');
data.addColumn('string', 'below_whom');
data.addColumn('string', 'ToolTip');
data.addRows(<?php echo json_encode($data); ?>);
var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));
chart.draw(data, {allowHtml:true});
}

I have been going through the documentation for quite sometime now and I am still clueless. I guess error is somewhere near addRows but I'm unable to trace it.
