human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "gmap drawing graphs as maps"
  Abstract: Information visualization is essential in making sense out of large data sets. Often, high-dimensional data are visualized as a collection of points in 2-dimensional space through dimensionality reduction techniques. However, these traditional methods often do not capture well the underlying structural information, clustering, and neighborhoods. In this paper, we describe GMap: a practical tool for visualizing relational data with geographic-like maps. We illustrate the effectiveness of this approach with examples from several domains All the maps referenced in this paper can be found in this http URL

Connected through hyperedge HE-1 (induced by source paper "an incremental dimensionality reduction method for visualizing streaming multidimensional data"):
  with members:
    - "progressive data science potential and challenges"
    - "online visual analytics of text streams"
    - "an overview of gradient descent optimization algorithms"
    - "approximated and user steerable tsne for progressive visual analytics"
    - "adadelta an adaptive learning rate method"
