Are there any best practices for securely managing sensitive data in PHP applications when using charting libraries?

When using charting libraries in PHP applications to display sensitive data, it's important to ensure that the data is securely managed to prevent unauthorized access or exposure. One best practice is to avoid passing sensitive data directly to the client-side code that renders the charts. Instead, the sensitive data should be securely retrieved and processed on the server-side before being passed to the charting library. 

<?php

// Retrieve sensitive data securely from the database or other source
$sensitiveData = retrieveSensitiveData();

// Process the sensitive data as needed
$processedData = processSensitiveData($sensitiveData);

// Pass the processed data to the charting library for rendering
echo "<script>";
echo "var chartData = " . json_encode($processedData) . ";";
echo "</script>";

// Function to retrieve sensitive data from a database (example)
function retrieveSensitiveData() {
    // Implement secure data retrieval logic here
}

// Function to process sensitive data (example)
function processSensitiveData($data) {
    // Implement data processing logic here
    return $data;
}

?>
