human: Given a node-centered hypergraph: <hypergraph>, where nodes represent authors and hyperedges represent groups of authors who co-authored the same paper.

Details of the hypergraph:
Center node: "Fast Interactive 3-D Graph Visualization"
  Abstract: We present a 3-D version of Gem [6], a randomized adaptive layout algorithm for nicely drawing undirected graphs, based on the spring-embedder paradigm [4]. The new version, Gem-3D, contains several improvements besides the adaptation to 3-D geometry.
