What are the potential pitfalls of using PHP to generate images for data visualization, and how can they be mitigated?

One potential pitfall of using PHP to generate images for data visualization is the risk of security vulnerabilities, such as injection attacks. To mitigate this risk, it is important to validate and sanitize user input before using it to generate images. 

// Validate and sanitize user input before using it to generate images
$user_input = $_GET['data'];

// Sanitize user input using filter_var
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Generate image using sanitized input
// Code to generate image here
