    could you explain what you mean with concept graph or upload a picture which illustrates your idea? And what did you try so far? – SeGa May 20 '18 at 12:54
  • concept graph in the sense, Generation of top keywords from the text data, those top keywords will be on nodes. – Abhishek May 20 '18 at 14:32
  • Maybe the `igraph` or `comato` or packages might help? – SeGa May 20 '18 at 15:56
