Just a trivial graph

From a meeting we discussed the git workflow and I was curious what Graph API would do with it's Trivial Graph Format.

[tgf engine:graphapi_png
PRD
ACC
TST
DEV
git
#
PRD PRD dbupdate, migrate, backup, restore
PRD ACC sync
ACC git pull
DEV git commit, push
TST git pull
PRD TST sync
TST PRD sync
PRD git pull
]

which results into Quite easy. But is it useful? Let me know.
