Arcs run from each source region to the event it covered that day. Thickness is the number of items; colour is the region's frame for the selected event (grey when it relays without a frame, or for other events).
Each cell compares how much of a region's output covers the event against what its total volume would predict (last 72 hours). Numbers are items. A hatched cell means the region published enough to be expected to cover the event, and didn't. That could be a choice, or a gap in our sources; check the board's source health before reading intent into it.
Last 7 days. Topic lift above 1 means the region covers that topic more than the world does. Emotive and authority rates are shares of items using loaded language or claiming authority ("the truth about", "fake news", "debunked"); the amber tick is the global rate. Record counts contradictions this region's outlets were on the right or wrong side of, once resolved.
Outlets with one owner are related voices: when they agree, that is one owner's line, not independent corroboration. Western state-funded international broadcasters (BBC World Service languages, DW, France 24, RFI, VOA, RFE/RL, RFA) are labelled the same way as Al Jazeera or TASS. Ownership changes often, so entries marked "check" are in flux.
Links come from four kinds of evidence in the last 14 days: near-identical headlines in the same language within a day, one outlet naming another as its source in any of 16 languages, relay chains traced in contested claims, and forums repeatedly pushing an outlet's links. Wires and majors that everyone cites are shown as reference hubs, not members. Membership describes observed co-amplification, not ownership or intent; treat a network as one voice when counting corroboration.
