The Citation Backbone

The atlas's hidden graph: places (right) and the sources that vouch for them (left). Two places are siblings when a shared source cites both. Hover a source to watch its reach light up; hover a place to see what holds it up. Place dots are colored by support — how many distinct sources cite them. The reds are the fragile pins, resting on a single citation. Click any node to open it in the Forensics panel.
