+
+`pw-dot`
+
+- Specify an output file, showing all object types:
+
+`pw-dot --output {{path/to/file.dot}} --all`
+
+- Print `.dot` graph to `stdout`, showing all object properties:
+
+`pw-dot --output - --detail`
+
+- Generate a graph from a remote instance, showing only linked objects:
+
+`pw-dot --remote {{remote_name}} --smart`
+
