Is there any solution for drawing simple graphs in LaTeX like the following? I came across tikz but couldn't figure out how to do it. Are there also possibilities to extend such graphs without caring too much about node distances etc?

  • One option: \documentclass{article} \usepackage{tikz} \usetikzlibrary{shapes,positioning} \tikzset{ myell/.style={ draw, ellipse } } \begin{document} \begin{tikzpicture}[node distance=1cm and 2cm] \node[myell] (sub) {Subject}; \node[myell,right=of sub] (obj) {Object}; \draw[->] (sub) -- node[above]{Predicate} (obj); \end{tikzpicture} \end{document}. – Gonzalo Medina Jun 11 '14 at 18:49
  • Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – user31729 Jun 11 '14 at 19:07
