This graph shows how connected each network is within a system.
Each node represents a network, and each edges represents a person overlapping them.
The darker the edge color, the more people spanning across the two communities.
This post explains the method in a bit more detail.
This graph was made in R, with the spere layout, using a Pajek file.
The data to make the pajek file was gathered from 44 different threads on a development forum…all on the same project.
A python script was used to compare the list of participants and the overlapping number.
