This paper analyses numerous graphic modelling methods —a more general term than choremes— developed from Roger Brunet’s theoretical positions. An examination of these applications makes it possible to define practical rules: mainly the use of a neutral geometrical basis and the identification of elementary structures, which are combined to describe spatial organisation. These principles are applied to Argentina, where six basic models describing six fields are identified. Their graphical combination provides an accurate picture of Argentina’s spatial organisation and their logical combination offers a tool for regionalisation.
