require_once 'phplot.php';

// Read CSV file
$data = array();
if (($handle = fopen("data.csv", "r")) !== FALSE) {
    while (($row = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $data[] = $row;
    }
    fclose($handle);
}

// Create PHPlot object
$plot = new PHPlot(800, 600);
$plot->SetDataValues($data);

// Set plot options
$plot->SetTitle("CSV Data Plot");
$plot->SetXTitle('X Axis');
$plot->SetYTitle('Y Axis');
