A chess diagram is graphic representation of a position in a chess game, using standardised symbols. Chess diagrams are widely used in chess publications as an aid to visualisation, or to aid the readers to verify that they are looking at the correct position on their chessboard or computer. The symbols used generally resemble the pieces of the standard Staunton chess set, although a number of different fonts have been used over the centuries.
