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 "regular labelings and geometric structures"):
  Abstract: Three types of geometric structure---grid triangulations, rectangular subdivisions, and orthogonal polyhedra---can each be described combinatorially by a regular labeling: an assignment of colors and orientations to the edges of an associated maximal or near-maximal planar graph. We briefly survey the connections and analogies between these three kinds of labelings, and their uses in designing efficient geometric algorithms.

Includes members:
  Member "steinitz theorems for simple orthogonal polyhedra":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "realization and connectivity of the graphs of origami flat foldings")
  Member "orientation constrained rectangular layouts":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "adjacency preserving spatial treemaps")
  Member "area universal rectangular layouts":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "computing stable demers cartograms")
  Member "compact floor planning via orderly spanning trees":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "the flip diameter of rectangulations and convex subdivisions")
