What best practices should be followed when using PHPlot in PHP scripts?

When using PHPlot in PHP scripts, it is important to follow best practices to ensure proper functionality and security. One key practice is to sanitize user input to prevent SQL injection attacks and other vulnerabilities. Additionally, make sure to validate input data to ensure it meets the expected format before passing it to PHPlot functions. Lastly, always handle errors gracefully by using try-catch blocks or error handling functions to prevent crashes and provide informative error messages to users.

// Sanitize user input to prevent SQL injection attacks
$user_input = mysqli_real_escape_string($conn, $_POST['user_input']);

// Validate input data before passing it to PHPlot functions
if (!is_numeric($user_input)) {
    die("Input must be a number");
}

// Handle errors gracefully using try-catch blocks
try {
    // PHPlot code here
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
