  This paper presents a novel exploration of the interaction between generative
AI models, visualization, and narrative generation processes, using OpenAI's
GPT as a case study. We look at the question "Where Does Generativeness Comes
From", which has a simple answer at the intersection of many domains. Drawing
on Umberto Eco's "Six Walks in the Fictional Woods", we engender a speculative,
transdisciplinary scientific narrative using ChatGPT in different roles: as an
information repository, a ghost writer, a scientific coach, among others. The
paper is written as a piling of plateaus where the titling of each
(sub-)section, the "teaser" images, the headers, and a biblock of text are
strata forming a narrative about narratives. To enrich our exposition, we
present a visualization prototype to analyze storyboarded narratives, and
extensive conversations with ChatGPT. Each link to a ChatGPT conversation is an
experiment on writing where we try to use different plugins and techniques to
investigate the topics that, ultimately form the content of this portable
document file. Our visualization uses a dataset of stories with scene
descriptions, textual descriptions of scenes (both generated by ChatGPT), and
images (generated by Stable Diffusion using scene descriptions as prompts). We
employ a simple graph-node diagram to try to make a "forest of narratives"
visible, an example of a vis4gen application that can be used to analyze the
output of Large Languange + Image Models.
