Co-authorship networks give us a sense of the strength of research collaborations. We used co-authorship data to visualize how top HIV/AIDS research institutions worked with one another, based on publications from June 2012 to September 2013. UCSF collaborations are indicated via red lines.

Visualization details: Data includes all known publications related to HIV/AIDS between June 2012 and September 2013 that includes co-authors from two or more institutions. We map each author to their institution, and the size of each institution corresponds with the number of HIV/AIDS publications its members co-authored in that time; only the most prolific institutions are shown to ensure readability of the image. The width of the lines connecting institutions corresponds to the number of publications that include co-authors from both of these institutions. Collaborations with UCSF researchers are indicated with red lines. Colors indicate clusters of institutions that often publish collaboratively, based on network modularity.
