Here, the residents of each of Angoulême's central parishes are clustered together by parish. These clusters are arranged so as to reflect the parishes' geographic proximity.
From this graph, it is easy to see how geography might have played a role in the formation of social networks. In aggregate, residents of a given parish are more likely to have relationships with members of an immediately neighboring parish than with residents of more distant ones. The small group of people from Petit St Cybard (in cyan), for instance, appear pulled away towards larger nearby hubs – those of Notre Dame de Beaulieu, St André, and St Jean. The outer parishes, including St Jacques, St Ausone, and St Yrieix, are more closely connected with inner, rather than other outer parishes.
