Linked Open Biomedical Investigations

I have started to work on the Linked Open Biomedical Investigations project with Jim McCusker.  So far i have just looked at the existing code in an attempt to understand it.  I plan on giving the project a considerable amount of time, which will include improving my d3 and javascript skills.  I am also trying to generalize the k-means function I used in the project in my previous post for use in this project.  I have run into difficulties, because of my lack of javascript knowledge.
