Vizul

Vizul is a conceptual framework used to describe the integration of visualization techniques with narrative elements in data presentation. It provides a language for specifying how visual components, data sources, and user interactions relate within a coherent story.

Core ideas of Vizul include modular components, sometimes referred to as vizules, that can be assembled into sequences or layouts. It also highlights a narrative layer that guides viewer attention and an interaction layer for filtering, exploration, and drill-down. Vizul emphasizes interoperability and composability, aiming to establish a shared vocabulary across tools for describing visualization work.

Applications of Vizul appear in education, where it helps explain how to structure data stories; in design practice, where it informs prototyping and communication with stakeholders; and in research, where it offers a framework for evaluating visualization storytelling and user engagement.

History and status of Vizul reflect its existence mainly in theoretical discussions about visualization and storytelling. There is no single formal standard or widely adopted implementation. Interpretations of Vizul vary across communities, ranging from high-level guidelines to practical workflows, which contributes to a spectrum of how it is applied in different contexts.
