While node-states-8.dot has two digraphs, dot(1) command can not
properly handle multiple graphs in a DOT file.
Use subgraphs and merge them into a single graph.

Hi Jon,
I happened to spot a broken DOT script at the bottom of
https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html
and managed to fix it.
DRBD DRIVER maintainers,
If I'm missing something here, please let me know.
Thanks, Akira
