human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "d3 reducible graphs"):
  Abstract: We describe two local reduction rules that can be used to recognize Halin graphs in linear time, avoiding the general-purpose planarity testing step of previous linear time Halin graph recognition algorithms. The same two rules can also be used to recognize a broader class of polyhedral graphs, which we call D3-reducible graphs. These graphs are the dual graphs of the polyhedra formed by gluing pyramids together on their triangular faces; their treewidth is bounded, and they necessarily have Lombardi drawings.

Includes members:
  Member "a planarity test via construction sequences":
    also connected through other hyperedges:
      (none)
  Member "lombardi drawings of graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "bipartite and series parallel graphs without planar lombardi drawings")
