Bibliographic Graphs

I just made a Mathematica program to generate the citation graph for scientific academic publications given a specific keyword (and some upper limit on the number of publications to treat). Some examples for three areas of my own interest are shown below

• Key word: "Bures measure"

• The same job done for  "Haar measure" 

It seems that the research done for the "Haar measure" is made of several unconnected niches. However, I expect that they will find some connection as I let the program run for more time.

• One final example for "Quantum control"

Bibliographic research is now easier because I can put the mouse on the top of each node and see what paper is that. Something nice would be to output the whole bibtex file.
