You have had recommendations for graphviz (dot etc.) and plantuml
already.  Those are very good suggestions and I use them all the
time.  For more general drawings, and given that you want something
programmatic, I would also suggest tikz (in LaTeX) as it's very powerful
(but then harder to do some simple things that graphiz/plantuml will do
very easily).

#+begin_export latex
\begin{tikzpicture}[node distance=4cm,minimum size=2cm]
\node[draw,fill=blue!20!white] (humanities) {Humanities};
\node[draw,fill=blue!20!white] (tools) [right of=humanities]
{\parbox{3cm}{Computing \\ Tools and \\ Methodologies}}
edge [->,out=270,in=270,very thick,red] (humanities)
edge [<-,out=90,in=90,very thick,red] (humanities);
\end{tikzpicture}
#+end_export
