What are some considerations to keep in mind when integrating jQuery AJAX functionality with PHP scripts for dynamic data visualization on the web?

When integrating jQuery AJAX functionality with PHP scripts for dynamic data visualization on the web, it is important to consider security measures to prevent vulnerabilities like SQL injection. Additionally, ensure that the PHP scripts are properly structured to handle the incoming data from the AJAX requests and return the appropriate response for visualization on the front end. 

<?php
// Example PHP script to handle AJAX request for dynamic data visualization

// Check if the request is an AJAX request
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    
    // Sanitize and validate input data
    $data = isset($_POST['data']) ? filter_var($_POST['data'], FILTER_SANITIZE_STRING) : '';

    // Perform necessary operations with the data (e.g. query a database)
    
    // Return the response in JSON format
    $response = array('success' => true, 'message' => 'Data processed successfully');
    echo json_encode($response);
    exit;
} else {
    // Handle non-AJAX requests
    // Redirect or display an error message
}
?>
