The author focuses on the methods of graphic (visual) coding of narrative polyphony in English postmodern fiction text. Resting on integrative interdisciplinary approach applied to the study of the issue under analysis, the author substantiates that the graphic surface of postmodern fiction text bears a particular layout, perspective and store of graphic (visual) signs originating from heterogeneous semiotic modes, both verbal and nonverbal. In this paper, the author defines and classifies visual signs as units of graphic coding of narrative polyphony in English postmodern multimodal fiction text. Graphic signs do not only change the graphic surface of the text, but also shape its new narrative structure, both of which construct polysemantic content of the text. Sinking into multimodal research, the author provides a study of the nature of graphic innovations as text units functioning on various text levels, both as attractors and distractors of its coded content that mirror linguistic norm democratization. By illustrating the applied methods in a text fragment from the English multimodal polyphonic fiction narrative, the author concludes that graphic coding units manifest postmodern fiction text as a synergetic whole in that the latter is a self-organized non-linear dissipative system that generates multiple ways of deconstructive text interpretation manipulating the reader. The author strongly believes that the findings may generate consequent research in the field of multimodal narratology.
