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 "on the density of 3 planar graphs"):
  Abstract: A $k$-planar graph is one that can be drawn in the plane such that every edge is crossed at most $k$ times. For $k \leq 4$, Path and T\'oth proved a bound of $(k+3)(n-2)$ on the total number of edges of a $k$-planar graph, which is tight for $k=1,2$. For $k=3$, we improve their bound from $6n-12$ to $\frac{11}{2}n-11$ and we also show that this is tight for multi-graphs with no homotopic edges.

Includes members:
  Member "planar octilinear drawings with one bend per edge":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "drawing subcubic 1 planar graphs with few bends few slopes and large angles")
  Member "1 visibility representations of 1 planar graphs":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fan crossing free graphs")
  Member "on the number of edges of fan crossing free graphs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "efficient generation of different topological representations of graphs beyond planarity")
  Member "notes on large angle crossing graphs":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "graphs with large total angular resolution")
