For this and many similar applications (Hasse diagrams, one-off characters like inverted ampersand, etc.), Latex's picture environment is a remarkably expressive language, permitting a self-contained library of macros for drawing circuits to be implemented in 20 noncomment lines. See http://boole.stanford.edu/pub/sumprod.pdf http://boole.stanford.edu/pub/TEX/sumprod.tex for the circuit realization of sum and tensor product in chu(Set,2), which appeared in http://boole.stanford.edu/pub/gates.pdf (FOCS'93 Palo Alto) and http://boole.stanford.edu/pub/bud.pdf (TEMPUS'94 Budapest).
