------------------------------------------------------------------------------
--- Views a dot graph as PDF.
--- If the first argument is `(Just c)`, the command `c`
--- (e.g., "evince" or "okular --noraise") to view the
--- generated PDF is started in background, otherwise the viewer is not invoked.
--- The second argument is the step number and used to index the output files
--- if it is positive.
