Passionate Charts: Arguments for Empathetic Emotions in Data Vis
share
Aristotle has considered the art of communication as a balance of logos, ethos, and pathos. While in science, logos (reason) and, recently also, ethos (morality) are discussed as aspects not to be neglected, pathos (feeling) is seen critically. In this work, we take a historical perspective on pathos and weigh the pros and cons of applying this rhetorical concept to the field of data visualizations. To better understand data, connecting it to the human way of thinking is imperative - appealing to emotions is one building block. The theoretical and empirical basis originates from different scientific fields, like social sciences, economics, and humanities. Tangible techniques to target empathetic emotions in data visualizations are introduced, as well as other rhetorical devices, such as interactivity and contextual framing, are highlighted. Researching these different approaches can provide new insights regarding the creation and influence of empathetic emotions in data visualizations.
