Temporal evolution of daily network components of Twitter election users. (a) Sketch representing the weakly (red) and strongly (green) connected giant components and the corona (black). (b) Influence daily network reconstructed from our Twitter dataset. The strongly connected giant component (green) is the largest maximal set of nodes where there exists a path in both directions between each pair of nodes. The weakly connected giant component (red) is the largest maximal set of nodes where there exists a path in at least one direction between each pair of nodes. The corona (black) is formed by the smaller components. (c) Total number of users in the daily strongly connected giant component (SCGC) versus time, (d) weakly connected giant component (WCGC) and (e) the corona, i.e. the rest of the components (displayed in black in (a) and (b)). The number of new users arriving in each compartment is shown in green. New users arrive principally in the weakly connected giant component or the corona. The shaded areas represents important events: the Associated Press announcing of Clinton winning the nomination (June 6), Bernie Sanders officially terminating his campaign and endorsing Clinton (July 12), the Republican (June 18–21) and Democratic (June 25–28) Conventions and the three presidential debates (September 26, October 9 and October 19).
