What are some best practices for using Google Charts in PHP applications?

When using Google Charts in PHP applications, it is important to properly format the data that will be passed to the chart. One best practice is to encode the data in JSON format before passing it to the Google Charts API. This ensures that the data is structured correctly for the chart to render properly. 

// Sample data array
$data = [
    ['Year', 'Sales', 'Expenses'],
    ['2014', 1000, 400],
    ['2015', 1170, 460],
    ['2016', 660, 1120],
    ['2017', 1030, 540]
];

// Encode data array to JSON
$jsonData = json_encode($data);

// Pass the JSON data to the Google Charts API
echo "<script type='text/javascript'>
        google.charts.load('current', {'packages':['corechart']});
        google.charts.setOnLoadCallback(drawChart);

        function drawChart() {
            var data = google.visualization.arrayToDataTable($jsonData);

            var options = {
                title: 'Company Performance',
                curveType: 'function',
                legend: { position: 'bottom' }
            };

            var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

            chart.draw(data, options);
        }
      </script>";
