We recommend clicking here or the "Source" tab below the visualization which will open the network in a separate browser window for easier viewing. Users can hover the cursor over terms and authors of interest. Clicking on nodes will bring up additional information. Users can also zoom in and out to areas of interest in the network using the magnifying glass icons at the bottom of the visualization. A search option allows users to search for terms of interest (if a given keyword is in the underlying network data, it will be highlighted in the visualization). Labeling of nodes was done to maintain legibility of the graph. If a given node or cluster of nodes appears without a label, users can simply zoom-in and the labels will appear automatically.
The network is visualized using an algorithm that puts the authors and keywords with the most connections to one another towards the center of the network. The least connected authors and keywords are pushed to the peripheries of the network. The full procedure for generating this visualization can be found here.
This visualization offers a wealth of information to help users orient themselves in the complex scholarly debates framing the issue of transboudnary movements of e-waste. For example, clicking on an author node (blue) will highlight the keywords associated with that authors work. It will also launch a side panel that offers information about the author including institutional affiliation at the time of publication, the source title(s) of documents published by that author, and a list of keywords associated with the author's published work.
Users are encouraged to explore this and other graphs to help orient themselves in the controversy and to ask questions about how the issue is shaped or framed by actors in the scholarly literature. Who are the most prominent authors (those near the center of the graph)? What institutional affiliations are most prominent? How are prominent authors situated with respect to keywords?
