Access to information is increasing rapidly, and data visualizations are becoming increasingly common as a way to communicate sum- maries of large datasets, especially in media designed for the general public. Accompanying this rise in visualization is a need for vi- sualization literacy. In this work we survey the current body of research on visualization literacy to find current research themes and guide future work. We found three themes of visualization liter- acy: interpretation, construction, and believability. Construction and believability are not traditionally discussed in visualization literacy research. We analyzed participant pools for visualization literacy user studies and found them to be lacking in diversity in gender and sex, age, education level, and recruitment country.
