Nodes seed from UMAP coords, so small tweaks mostly refine locally. Hit Shake to disturb positions and see forces rebuild layout.
Point = author · position = mean SPECTER2 embedding of their papers → UMAP 2D · size = # papers · color = Leiden community (coauthor or semantic, toggleable)
Nearby points work on similar topics. marks phantom collaborators: top semantic neighbors who have not directly coauthored with this author — same research turf, no shared paper yet.
