I know that DAGMan can assist you in visualizing a DAG with dor.
I would like specify a CYCLIC graph with DAGMan instead and then
visualize it with dot.
Is this possible and how?
It should be sort of possible. If you have DAGMAN_STARTUP_CYCLE_DETECT
set to false (or not set at all), DAGMan won't actually check for a cycle
in the graph at startup time. (The default is false because that's a
pretty expensive operation.)
So DAGMan will run the workflow until it hits the point when it finds out
that there's a cycle. If you have it set up to generate a DOT file
you should get something you can view in dot. I suspect that you won't
get an update right at the end, though.
I don't think we've ever tried this, so take this info with a grain of
salt. But I think it's worth trying, anyhow.
