Katz uses grids, tax forms, sports scores, prescription drug leaflets, voting ballots, and other documents to demonstrate both correct and incorrect examples of organization, proximity, and hierarchy. Much of the discussion here echoes the ideas put forth in Kress and Van Leeuwen's chapter, "The Meaning of Composition" from their book Reading Images. Katz explains the concept of organization as providing structure to information so the user can intuitively and quickly grasp the meaning of the graphic.
