pw-dot documentation: legend
The pw-dot tool is used for making a Graphviz representation of the PipeWire object graph. The documentation tells about how to use it as a CLI application, but doesn't tell about what specific graph elements mean on it.
I think it would be helpful to have documentation on how to interpret the graph:
- what do the certain colors mean
- what do the certain types of arrows mean (it looks like it is also context dependent, in case of the dashed arrow at least)
- what do those nodes of the graph mean which don't have an object on the PipeWire object graph according to pw-dump (e.g. the white box with the client_id and factory_id, drawn inside PW Nodes in
--all
mode) - possibly others
These questions arose while writing my own documentation on the tool
