Designing Annotations in Visualization: Considerations from Visualization Practitioners and Educators
🤖 AI Summary
This study addresses a critical gap in visualization research by systematically investigating the design decision-making processes behind annotations—a dimension often overlooked despite extensive focus on their visual forms. Through a two-phase qualitative study involving semi-structured interviews with ten practitioners and seven educators, the work integrates practical and pedagogical perspectives to uncover tacit expert knowledge in annotation design. The authors reconceptualize annotations not merely as static visual elements but as dynamic design activities, revealing key trade-offs among clarity, guidance, and viewer agency. Building on these insights, they formulate a set of heuristic strategies and context-sensitive judgment principles. These contributions provide both theoretical grounding and practical support for the development of visualization tools and design guidelines.
📝 Abstract
Annotation is a central mechanism in visualization design that enables people to communicate key insights. Prior research has provided essential accounts of the visual forms annotations take, but less attention has been paid to the decisions behind them. This paper examines how annotations are designed in practice and how educators reflect on those practices. We conducted a two-phase qualitative study: interviews with ten practitioners from diverse backgrounds revealed the heuristics they draw on when creating annotations, and interviews with seven visualization educators offered complementary perspectives situated within broader concerns of clarity, guidance, and viewer agency. These studies provide a systematic account of annotation design knowledge in professional settings, highlighting the considerations, trade-offs, and contextual judgments that shape the use of annotations. By making this tacit expertise explicit, our work complements prior form-focused studies, strengthens understanding of annotation as a design activity, and points to opportunities for improved tool and guideline support.
