FIG. 5. — Reconstruction of the directed network of influence between $N = 1833$ twitter users from 58224 retweets, using a SI infection model. The hierarchical division represents the inferred fit of the nested DC-SBM (see Refs. [51,52] for details on the layout algorithm), and the edge colors indicate the infection probabilities $τ_{i j}$ as shown in the legend. The text labels show the dominating country membership for the users in each group.
