tikz-cd — Commutative diagrams with TikZ ======================================== The general-purpose drawing package [TikZ][pgf] can be used to typeset commutative diagrams and other kinds of mathematical pictures, generating high-quality results. This TikZ library facilitates the creation of such diagrams by providing a convenient set of macros and reasonable default settings. It can be used in plain TeX, LaTeX and ConTeXt. See [the manual][tikz-cd-doc] for further details and many examples.
