tikz-cd – Create com­mu­ta­tive di­a­grams with TikZ

The gen­eral-pur­pose draw­ing pack­age TiKZ can be used to type­set com­mu­ta­tive di­a­grams and other kinds of math­e­mat­i­cal pic­tures, gen­er­at­ing high-qual­ity re­sults. The pur­pose of this pack­age is to make the pro­cess of cre­ation of such di­a­grams eas­ier by pro­vid­ing a con­ve­nient set of macros and rea­son­able de­fault set­tings. This pack­age also in­cludes an ar­row tip li­brary that match closely the ar­rows present in the Com­puter Modern type­face.
