Abstract

There is scope for diagrams in most subject areas, but in the sciences — physics, chemistry, biology, geography, geology and so on — they are of central importance. Diagrams of apparatus, equipment and experimental structures are commonplace, while the individual sciences often have specific diagram requirements:

Physics:	electrical circuits optical diagrams
Chemistry:	crystal structure comparative tables (such as the ‘Periodic Table’)
Biology:	cell and tissue diagrams ‘chain diagrams’ (such as food chains)
Geography/Geology:	mineral structures maps
