D&D Feat Progression

D&D (3rd edition) has a number of character capabilities which are handled as binary "feats". The D&D Players Handbook has feats listed semi-alphabetically and described in alphabetical order. This organization does not illustrate well the trees of dependence for combat-related feats. It also does not group by area. Below the feats are listed organized by field (combat/magic/other) and prerequisites.
