  The Open-Source Software community has become the center of attention for
many researchers, who are investigating various aspects of collaboration in
this extremely large ecosystem. Due to its size, it is difficult to grasp
whether or not it has structure, and if so, what it may be. Our hackathon
project aims to facilitate the understanding of the developer collaboration
structure and relationships among projects based on the bi-graph of what
projects developers contribute to by providing an interactive collaboration
graph of this ecosystem, using the data obtained from World of Code
infrastructure. Our attempts to visualize the entirety of projects and
developers were stymied by the inability of the layout and visualization tools
to process the exceedingly large scale of the full graph. We used WoC to filter
the nodes (developers and projects) and edges (developer contributions to a
project) to reduce the scale of the graph that made it amenable to an
interactive visualization and published the resulting visualizations. We plan
to apply hierarchical approaches to be able to incorporate the entire data in
the interactive visualizations and also to evaluate the utility of such
visualizations for several tasks.
