What are some common pitfalls to avoid when working with arrays in PHP for data visualization?

One common pitfall to avoid when working with arrays in PHP for data visualization is not properly checking if the array is empty before trying to access its elements. This can lead to errors or warnings being displayed. To solve this issue, always use functions like `empty()` or `isset()` to check if an array is empty before trying to access its elements. 

// Check if the array is empty before accessing its elements
if (!empty($array)) {
    // Access the elements of the array
    foreach ($array as $element) {
        // Process the elements for data visualization
    }
} else {
    // Handle the case when the array is empty
    echo "The array is empty.";
}
