The core of the game is making correct decisions.

There are preflop decisions and postflop decisions. A chart can quickly and easily provide input on one factor that goes into the preflop decision: an objective evaluation of your hand strength. Other factors include your position, your position relative to tight or loose players, what your postflop position will be, whether the players who have acted are tight or loose, whether the players who have yet to act are tight or loose, the size of the pot, the likely size of the pot, whether your hand plays well against the likely number of opponents seeing the flop, etc.

More and/or "better" charts aren't going to improve anyone's game. A chart is a tool. A good player, like a good craftsman, acquires more and more tools. If all you have is a hammer, everything looks like a nail.
