23. What is at stake in data visualization? A feminist critique of the rhetorical power of data visualizations in the media

Data visualizations are powerful semiotic resources, which, it is sometimes claimed, have the power to change the world. This chapter argues that to understand this power we need to consider the uses to which visualizations have been put. Using visualizations relating to abortion as a case study alongside Klein and D’Ignazio’s notion of a ‘Bring Back the Bodies’ in data visualization, I argue that visualizations tell a narrow story, removing contextual detail and omitting to ask questions important to women’s health. To grasp the signif icance of this I propose a new body issue: the neglect of the viewer and those affected by decisions taken based on visualized data. Far from being a simple device to graphically display numerical data, therefore, there are important social and ethical issues at stake in data visualization.
