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 "increasing chord graphs on point sets"):
  Abstract: We tackle the problem of constructing increasing-chord graphs spanning point sets. We prove that, for every point set P with n points, there exists an increasing-chord planar graph with O(n) Steiner points spanning P. Further, we prove that, for every convex point set P with n points, there exists an increasing-chord graph with O(n log n) edges (and with no Steiner points) spanning P.

Includes members:
  Member "on self approaching and increasing chord drawings of 3 connected planar graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "drawing graphs as spanners")
  Member "self approaching graphs":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "drawing graphs as spanners")
