Abstract
Data stories integrate compelling visual content to communicate data insights in the form of narratives. The narrative structure of a data story serves as the backbone that determines its expressiveness, and it can largely influence how audiences perceive the insights. Freytag's Pyramid is a classic narrative structure that has been widely used in film and literature. While there are continuous recommendations and discussions about applying Freytag's Pyramid to data stories, there is little systematic and practical guidance for data story creators on how to use Freytag's Pyramid for structured data story creation. To bridge this gap, we examined how existing practices apply Freytag's Pyramid through analyzing stories extracted from 103 data videos. Based on our findings, we propose a design space of narrative patterns, data flows, and visual communications to provide practical guidance on achieving narrative intents, organizing data facts, and selecting visual design techniques through the story creation process. We evaluated the proposed design space through a workshop with 25 participants. The results show that our design space provides a clear framework for rapid storyboarding of data stories with Freytag's Pyramid.
