and some implementation for one point (it is easy to reproduce it to
large datasets of points - not tested):

$tile = GoogleMapUtility::toTileXY($x,$y,$zoom);
//$rect = GoogleMapUtility::getTileRect($tile->x,$tile->y,$zoom);
$point = GoogleMapUtility::toZoomedPixelCoords($x,$y,$zoom);
$xp = $point->x - (GoogleMapUtility::TILE_SIZE * $tile->x);
$yp = $point->y - (GoogleMapUtility::TILE_SIZE * $tile->y);
ob_start();
$im = imagecreate(GoogleMapUtility::TILE_SIZE, GoogleMapUtility::TILE_SIZE);
$blank = imagecolorallocate( $im, 0, 0, 0 );
imagefilledrectangle( $im, 0, 0, GoogleMapUtility::TILE_SIZE,
GoogleMapUtility::TILE_SIZE, $blank );
$red = imagecolorallocate($im, 255, 0, 0);
imagefilledellipse($im,$xp-5,$yp-5,10,10,$red);
imagecolortransparent($im, $blank);
imagepng($im);
imagedestroy($im);

$imagedata = ob_get_flush();
file_put_contents("file.png", $imagedata);
