RRDGraph::__construct 메서드에서 $rrdfile 변수는 RRD 파일을 가리키는 경로를 저장하는 변수입니다.
$rrdfile 변수는 RRDGraph 클래스의 생성자 메서드에서 초기화되며, RRD 파일의 경로를 지정하는 데 사용됩니다.
예를 들어, RRD 파일이 `/var/lib/rrd/my_rrd.rrd` 경로에 위치한다면, `$rrdfile` 변수는 이 경로를 저장합니다.

$rrd = new RRDGraph('/var/lib/rrd/my_rrd.rrd');
$rrdfile 변수를 초기화하는 부분은 다음과 같습니다.
```php
