Swiss Data Story:

The official (and entirely made-up) census of a Swiss lake town’s 1’427 pigeons, one dot per bird, set on a strict grid in red and black. The flock rearranges itself into a waffle chart, a 24-hour rose, packed clusters, a commuter map and a final donut that names the man behind it all. Hover any dot to meet that pigeon, click to follow it through every chart, or swipe fast to startle the flock.
