This was a stunning piece about the Fire at the Notre Dame Cathedral. It looks like the visualisation team at the NYT threw everything at it but the kitchen sink, but this is a visualisation where the data is a timeline of moments sourced from reporting work done by journalists nailing down a series of events drawn from a confusing medley. The use of user-generated content was spectacular in capturing the sense that the world was watching, and the illustrations from the sketchbook of a firefighter are a nice touch.
