-## Graph Tri-State
-
-The `enable_graph` parameter follows a three-level precedence:
-
-```
---no-graph  (explicit disable)  >  --graph  (explicit enable)  >  config default
-```
-
-If `--no-graph` is passed, graph is disabled regardless of other settings. If `--graph` is passed (without `--no-graph`), graph is enabled. If neither is passed, the config value `defaults.enable_graph` is used.
