What is the best practice for updating a graphic generated by PHP at regular intervals?

To update a graphic generated by PHP at regular intervals, you can use AJAX to make periodic requests to the server for updated data and then refresh the graphic on the client side. This allows for real-time updates without the need to constantly refresh the entire page. 

<?php
// PHP code to generate the graphic
// This code should output the graphic image

// Example AJAX request to update the graphic every 5 seconds
?>
<script>
setInterval(function(){
    // AJAX request to fetch updated data
    $.ajax({
        url: 'update_graphic_data.php',
        type: 'GET',
        success: function(data) {
            // Update the graphic with the new data
            // For example, if using an <img> tag with id="graphic"
            $('#graphic').attr('src', 'path/to/updated/graphic.php?data=' + data);
        }
    });
}, 5000); // 5 seconds interval
</script>
