- Generate a graph to `pw.dot` file:

`pw-dot`

- Read objects from `pw-dump` JSON file:

`pw-dot {{[-j|--json]}} {{path/to/file.json}}`

- Specify an output file, showing all object types:

`pw-dot {{[-o|--output]}} {{path/to/file.dot}} {{[-a|--all]}}`

- Print `.dot` graph to `stdout`, showing all object properties:

`pw-dot {{[-o|--output]}} - {{[-d|--detail]}}`

- Generate a graph from a remote instance, showing only linked objects:

`pw-dot {{[-r|--remote]}} {{remote_name}} {{[-s|--smart]}}`

- Lay the graph from left to right, instead of dot's default top to bottom:

`pw-dot {{[-L|--lr]}}`

- Lay the graph using 90-degree angles in edges:

`pw-dot {{[-9|--90]}}`

- Display help:

`pw-dot {{[-h|--help]}}`
