How can PHP beginners avoid pitfalls when trying to generate arrays from SQL data for charting in JPchart?

Beginners can avoid pitfalls when generating arrays from SQL data for charting in JPchart by properly fetching and formatting the data from the database before passing it to the charting library. It is important to ensure that the data is in the correct format for the charting library to interpret it correctly. 

// Fetch data from the database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Create an array to store the data
$data = array();

// Loop through the results and format the data
while($row = mysqli_fetch_assoc($result)) {
    $data[] = array(
        'label' => $row['label'],
        'value' => $row['value']
    );
}

// Pass the formatted data to JPchart for charting
// Example usage: $chart->setData($data);
