chem­fig – Draw molecules with easy syn­tax

The pack­age pro­vides the com­mand \chem­fig{<code>}, which draws molecules us­ing the tikz pack­age. The <code> ar­gu­ment pro­vides in­struc­tions for the draw­ing op­er­a­tion.
While the di­a­grams pro­duced are es­sen­tially 2-di­men­sional, the pack­age sup­ports many of the con­ven­tional no­ta­tions for il­lus­trat­ing the 3-di­men­sional lay­out of a molecule.
The pack­age uses TikZ for its ac­tual draw­ing op­er­a­tions.
