What potential pitfalls should be considered when implementing weather data visualization using PHP?

One potential pitfall when implementing weather data visualization using PHP is the risk of exposing sensitive API keys or credentials in your code. To mitigate this risk, it is recommended to store your API keys securely and not hardcode them directly in your PHP files. Instead, consider using environment variables or a configuration file outside of your project directory to store and access your API keys. 

// Store your API key in a separate configuration file
$config = parse_ini_file('config.ini');

// Access your API key securely
$apiKey = $config['API_KEY'];
