Figure 4

Alluvial plots showing how accounts deemed influential at the beginning tend to stay influential over time. The alluvial flow in this chart shows that most node that were influential at the beginning tend to stay near the top—the green flows descend only slightly and never become unimportant (blue). The orange flows (ones that were fairly influential at the beginning) tend to mostly stay flat or move downward but not too much. The blue flows (not influential at the beginning) stay mostly flat though some upward movement can make them moderately influential (orange) but rarely highly influential (green).
