Does anyone know a tool for drawing collaboratation graphs?
To be more specific, when you enter a new field (subfields) you would like to know who is who in this subfield which publications are pivotal in the fields etc. A mathematician can use tools like arXiv, mathsci.net or Google scholar. They are great but also a bit limited. I think it would be great to have a possibility to draw graphs which depicts connections.
I found such tool: http://pubnet.gersteinlab.org/gallery.html , but it works only for publications in medicine. Anything like that in math?
