I'm looking for a PhD position. Of course I'm reading and following the papers of the field to get to know the community. Is there a tool to visualize a citation/co-author network (or at least a database I could visualize myself)? I have looked into tools like CitNetExplorer and VosViewer. Csauthors.net is also a nice tool, but it is limited to showing only a path between two researchers instead of a full graph.
Essentially, I would like to map all collaborations of the researchers to get a feeling for where the hot spots are and where the niches are.
