This docstring should be moved up a line and should only consist of
a single set of double quotes.

I'd prefer to have this as a customizable variable, as is done with snakemake-program.

(when (equal dot "")
(error "You do not have dot (graphviz) on your emacs path!")))
(let* ((fname (buffer-file-name))
(graphname (concat (buffer-file-name) ".pdf"))
(graph-command (concat "snakemake --dag --snakefile " fname " | dot -Tpdf > " graphname)))

Hmm, but this is limited to creating the graph for the first rule of
the Snakefile, right? Instead, a compile command could be constructed
(similar to what is done in snakemake-compile). This could default
to naming the output something like <rule>-dag.pdf, but the user could
edit the compile command further.
