Google Charts is a simple API that lets you create various types of charts. To create a chart, you just need to call a URL with specific parameters and you receive an image back.

This is greatly simplified with a PHP class.

$data = array( 'IE7' => 22, 'IE6' => 30.7, 'IE5' => 1.7, 'Firefox' => 36.5, 'Mozilla' => 1.1, 'Safari' => 2, 'Opera' => 1.4, );


$chart = new googChart();

$chart->setChartAttrs( array(

    'type' => 'pie',

    'data' => $data,

    'size' => array( 300, 200 )

    ));

echo $chart;

Die Ausgabe:
Chart

A practical example is the calculation of distances. In some projects I calculated this with PHP.

It can also be done directly with SQL
SELECT *, SQRT(POW(L2.lat - L1.lat, 2) + POW(L2.lng - L1.lng, 2)) AS Distance
