Nomography is the craft of designing nomograms — graphical calculating devices that represent mathematical relationships between variables through graduated scales arranged so that a straightedge, connector, or other alignment reveals the solution. A nomogram maps numerical quantities to positions on geometric scales (parallel, radial, curved, or combined) according to a specific algebraic or functional relationship, allowing users to read results by drawing a line or sliding a bridge. The parameters of a nomogram are the scale equations, their geometric layout, and the alignment rule that connects them; the persistence mechanism is transmission through engineering and technical drawing curricula, professional practice, and published reference tables — a practitioner learns the scale mathematics, constructs the chart, and distributes it for use.

Definition
Why it is in scope
A human-made practice for representing multivariable relationships through graphical computation devices. Built to persist through engineering handbooks, educational curricula, and field-reference cards used by technicians and designers.

Nomography is a specific kind of method — a graphical technique for solving mathematical equations. A competent speaker would say 'nomography is a method.' Nearest kind: method.

Nomography is a specific graphical technique for solving equations. Mathematics existed first (ancient) and fed into the development of nomography as a specialized mathematical practice. Which-came-first test: mathematics predates nomography by millennia.

Remove diagrams right now — does nomography stop operating? Yes. Nomography IS the practice of solving equations via calibrated graphical plots. Without diagrams, nomography ceases to function. The removal test passes.

Nomography solves equations through calibrated graphical plots. Remove mathematics and the equations it operates on cease to exist — nomography has no substance without the mathematical relationships it visualizes. The removal test: no mathematics = no equations = nomography stops operating entirely.

Removal test (Law 8): a nomogram maps numerical quantities to scale positions to reveal mathematical relationships. Remove measurement and there are no quantities to map — nomography stops operating. This is not meta-level sayability but object-level function: nomography needs measurement to function. The note tests removal of the target and shows collapse of the source.
