Bar = share of the extra attention over the whole window; the tick marks the share on the peak day alone, where the two differ.
How unusual it was
This was above 44% of all days since 2020, and the highest since Thursday 17 July 2025.
How far it spread

Bars start at 1× — normal readership for that vessel type, the weeks before the incident. Grey = no clear lift. "Over time" shows each group's daily readers through the window; "All 12 articles" breaks the six groups back into their members.
