Fddiagram – Automatic Functional Dependency diagrams from a plain-text list

This package typesets Functional Dependency (FD) diagrams, as commonly used when teaching or checking relational database normalisation, directly from a plain-text list of dependencies in the form left-hand side → right-hand side. The attribute universe, its ordering, and the layout of each dependency’s diagram are derived automatically: no manual coordinates or column ordering are required. Options, settable either when the package is loaded or per diagram, control spacing, colours, arrow style, label alignment, and optional dotted or dashed guide lines connecting each mark back to its attribute. The package requires TikZ, xparse and l3keys2e, all part of any current TeX distribution.
