Chapter 122the change in the meaning of specific visualisations that travel across contexts. Van Beek and colleagues, however, also note modifications made in visualisations. Conceptually, Van Beek and colleagues associate changes in meaning with the dynamic nature of visual framing and the fact that framing occurs in different stages of visualisations’ meaning-making. In doing so, they pay much attention to the connectivity of the different stages. Niederer (2018) studies the change in visualisations’ meaning over time from a slightly different angle. Niederer considers networked visual content a subject of study. For her, changes in visual content networked by means of, for example, links between pages, offer answers to questions about meaning that is changing over time, for example, as a response to specific political events.In this dissertation, I study the circulation of specific visualisations, similar to Aiello and Parry (2020) and Van Beek et al. (2020), and changes in visual networked content, similar to Niederer (2018). In line with Van Beek et al., I acknowledge the connectivity of the meaning-making stages. However, I extend this acknowledgement to also include means of meaning-making other than visual framing.The circulation aspect is crucial for a complete understanding of the meaning of a visualisation, especially given the ever-intensifying process of circulation on social media platforms (Rose, 2016, p. 288). Furthermore, in the context of policy controversies, a change in the meaning of visualisations while they circulate can be significant because it can reveal an interaction between actors and negotiations between them about the meaning of the policy issue (Rojas-Padilla et al., 2022). Hence, the third sub-question is:(How) does the meaning of visualisations related to a policy controversy change when they circulate?1.5 Method1.5.1 Case selectionIn answering the research questions, the empirical chapters of this thesis study multiple cases of emerging and more developed technologies in energy and Efrat.indd 22 19-09-2023 09:47
