I am trying a LaTeX export, but I get the following error:
org-babel-exp processing...
executing Dot code block...
Wrote /tmp/babel-18129i9i/ob-input-18129Nzr
Code block evaluation complete.

org-latex-compile: PDF file ./shell-scripting.pdf wasn't produced: [LaTeX
error]

Not very clear. What could be the problem?
