Got it working using this:
$ch = curl_init('http://chart.apis.google.com/chart?
chid='.md5(uniqid(rand(), true)).'&'.http_build_query($chart));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_POST,count($chart));
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query($chart));
$response = curl_exec($ch);
$file = fopen($filename, 'w+');
fwrite($file, $response);
fclose($file);
Just put all the params into the chart array.
