Fig. 6

A Sankey diagram showing the transitions of users from the pre-invasion network communities (left) to the invasion network communities (right). Rectangle height is proportional to the community size. Percentages on the right-hand side near the pre-invasion communities show the portion of users found in the corresponding invasion communities. Percentages on the left-hand side near the pre-invasion communities show the portion of users of the pre-invasion communities that are inactive in the invasion period. Percentages on the right-hand side of the invasion communities show the portion of users not previously present in the large communities of the pre-invasion network.
