The PreTeXt Guide

Commutative diagrams may be authored using the AMS LaTeX amscd⁴ package. While restricted in some ways, such as the lack of sloped or curved arrows, it has one important advantage over more general drawing tools. Support for HTML output comes from MathJax, and hence has accessible versions included in the output.

Typical use would be within an <me> element, so starting with \begin{CD}. Despite this being multi-line output, we have not chosen to integrate it within the more general md/mrow structure, but that decision can be revisited.
