[Tex/LaTex] How to make a block scheme with arrows in LaTeX

Question

I am new to LaTeX, I have searched in many forums, but can not find, how to depict block scheme like on the picture. Could you please give me hints or commands, which i can use in this case? And my LaTeX doesn't run tikzpicture package….
Thank you very much in advance.

Answer 1

No TikZ? No problem! :-)

Here's a solution using the built-in picture environment:

\documentclass{standalone}
\begin{document}
\begin{picture}(120,120)
\put(10,80){\framebox(100,15){Economic indicators}}
\put(60,80){\vector(0,-1){12.5}}
\put(10,52.5){\framebox(100,15){Social mood}}
\put(60,52.5){\vector(0,-1){12.5}}
\put(10,25){\framebox(100,15){Electoral results}}
\qbezier(9.8,87.5)(-5,60)(9.8,32.5)
\qbezier(110.2,87.5)(125,60)(110.2,32.5)
\put(110.2,87.5){\vector(-1,2){0}}
\put(9.8,32.5){\vector(1,-2){0}}
\end{picture}
\end{document}
