A Design Space for Visualization Onboarding in Data-Driven Stories

Data-Driven Stories (DDS) are stories that combine text and data portrayed as visualization in a narrative format. They are among the popular ways of communicating information by online medias nowadays. For DDS authors and designers, it's important to minimize the risk of misinterpreting visualizations by their readers. Visualization onboarding, embedding knowledge and guidance have been meant to provide adequate support for readers to understand visualizations as they progress through DDS. Onboarding is a continuous mechanism which involves various DDS elements and interactions on each step. Several previous studies attempted to identify and classify storytelling techniques in DDS. While these techniques prospect a satisfactory communication, it's not clear how they can be applied to facilitate the visualization understanding throughout the story. They rather conceptualized different aspects of storytelling individually, and as such, the chronology of onboarding steps has been missed. Although their techniques and design spaces represent a tangible level of abstraction, they will not benefit authors in the story design process. Authors either rely on their guess work or mimic previous DDS to accommodate support in their DDS scenarios. In this project, our overall goal is to propose a multidimensional design space for onboarding techniques in DDS that can benefit to authors during their design process.
