Network analysis: People and open source communities

Download to read offline

Data and code: https://github.com/geekygirldawn/oscon_2015

The real magic in any community comes from the people. I will show you tools and techniques for performing network analysis, to look at the people in your community along with the relationships between them. Why settle for boring numbers and line charts to describe your community when you can do cool visualizations that show how people connect within your open source community?
