Feature Request - Dependency Chain Export

[Murry-Ovo]

It would be great to be able to enter a series of tags, actions or select 'whole project' and be able to export the dependency chain that is created for these runs.

Can you clarify how you'd like this to be exported? Is dataform compile --json sufficient?

[Murry-Ovo]

I was thinking of a more visual representation, similar to the graphical view in the run logs, however a JSON output would also be useful

This would be a fun feature to make. CLI based text representations would be a bit ugly, because of the limits of scrolling and scaling. I think it would be better to use graphviz to create an image instead. For example:

• Add a new CLI option for --dot
• If that option is set, convert the compiled graph JSON format https://github.com/dataform-co/dataform/blob/c0d1a7400f4aed74f90e032149561a3027df0ea4/cli/index.ts#L329 to a dot file instead
  • A dotfile would instead like digraph { dataset.table1 -> dataset.table2 }
• If the --dot option is set, print the dot file output rather than the json output.
• Users can then use that dotfile as they wish - probably with the graphviz CLI https://graphviz.org/doc/info/command.html
  • Alternatively we could bundle graphViz in with the CLI, and make the image on demand https://github.com/ts-graphviz/node
