Our proposed half-day workshop will bring together communicative visualization practitioners with researchers from several fields to address the questions raised by the rapidly growing communicative uses of visualization (e.g. in-news graphics, information graphics). These questions span issues of audience, application, evaluation, understanding and practice. To encourage participation from communities that do not typically attend IEEE Visualization and write academic papers, we will not only accept short papers but also visual case studies, and recruit program committee members from those communities. We have organized this workshop before with great success: at VIS 2018 with around 70 participants and nine papers and posters, and at VIS 2019 with around 60 participants (the room was over capacity, with people turned away) and 13 papers and posters.
