What are the potential pitfalls of dynamically generating an organigram from xlsx data in PHP?

One potential pitfall of dynamically generating an organigram from xlsx data in PHP is the risk of exposing sensitive information if the xlsx file contains confidential data. To mitigate this risk, you can implement access control mechanisms to restrict who can view the organigram.

// Example code snippet implementing access control for dynamically generating an organigram from xlsx data
if($user->hasPermission('view_organigram')) {
    // Code to dynamically generate organigram from xlsx data
} else {
    echo "You do not have permission to view the organigram.";
}
