Was there a tool that automatically made workflow diagrams from the dag intos buway

Yes - someone presented this at this year's (virtual) Nextflow Summit. Can't recall who specifically ATM, but it was part of the "community" track. Isn't open source yet IIRC, but the plan is to make it so eventually. (my notes are sparse - b/c Nextflow Summit took place at 4am my local time)

Ya same. Okay will take a look
