7A | Digital Media and Storytelling in Higher Education between elements, and arrows can be used to show causality or hierarchies of concepts and data (Tversky, 2018). In visual storytelling, episodes can be replaced by symbols. An example is the partnership symbol in Figure 4 (two people facing each other shaking hands), which indicates to the receiver that there was a prior agreement between the partners before they started working together. For narratives which compare data, another effective visual tool is the juxtaposition of data series and the use of visual attributes (e.g., replacing countries with flags or replacing gender with biological sex symbols).

The viewer may be concerned by the infographic, leading to a reflection on his or her own situation. Thudt, Walny, Gschwandtner, Sykes, and Stasko (2018) argue that the advantage of DDS is that it allows recipients to experience the joy of discovery and find their own story with which to compare to the researcher's interpretation. Interactive visualizations in particular activate the interpretation of the recipient, who chooses the perspective or point of view from which
