This workshop focuses on 'data-visualization activities', especially methods and challenges for teaching and engaging with data visual-ization concepts, knowledge, and practices. For example, sketching aids designers to consider alternative ideas; manipulating tokens help students conceptualize quantities for data visualization; user interviews and discussions help developers understand requirements. Workshops, classes, or collaborations with domain experts, often include hands-on data visualization activities that involve analog or digital tools and materials and more or less well defined protocols. Recent years have seen the emergence of such data visualization activities in different contexts, including education, visualization design, activism, self-reflection, and interdisciplinary collaboration. However, the broad range of contexts and target audiences that Data-Vis activities have been applied to makes it difficult to collect and identify commonalities and build knowledge in a systematic way. Thus, the goals of this workshop are i) start building an understanding and to synthesize protocols and materials used to lead data vis activities, ii) to bring together researchers, practitioners, and educators from within and outside of the visualization community, iii) brainstorm, design, experience, and try novel activities, and to iv) discuss issues around goals, methods, audiences, materials, and evaluation for teaching data visualization.
