They are also commonly used in medical practice. E.g. to work out what's called the body mass index from a person's height and weight in drug dose calculations.
The reason for their use seems to be twofold  1, the people who use them do not know very much mathematics (at least of the school arithmetic kind); but 2, you can calculate with them whilst having both hands full!
An ancient book, "The Nomogram", Allcock & Jones, (Pitman, London, 1922) discusses the maths behind their construction. V interesting, and should be implementable in any software.
