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.
