If I select the "package" graph type, guix graph completes:

$ ./pre-inst-env guix graph --type=package p11-kit
digraph "Guix package" {
  "140299993452720" [label = "p11-kit@0.23.22", shape = box, fontname =
sans];
  "140299993452720" -> "140299993453072" [color = magenta];
  "140299993452720" -> "140300286436736" [color = magenta];
  "140299993452720" -> "140299980957936" [color = magenta];
  "140299993452720" -> "140299993453072" [color = magenta];
  "140299993453072" [label = "libtasn1@4.17.0", shape = box, fontname =
sans];
  "140299993453072" -> "140299983720224" [color = blue];
  "140299983720224" [label = "perl@5.34.0", shape = box, fontname =
sans];
  "140299983720224" -> "140299983567616" [color = red];
  "140299983567616" [label = "coreutils-minimal@8.32", shape = box,
fontname = sans];
  "140300286436736" [label = "pkg-config@0.29.2", shape = box, fontname
= sans];
  "140299980957936" [label = "libffi@3.3", shape = box, fontname =
sans];

}

Thank you for your python script! Unfortunately, it does not detect any
cycles here.
