+## Trackio snapshot
+
+The finished dataset is recorded in the single public Trackio run [`final-dataset-snapshot`](https://huggingface.co/spaces/NoeFlandre/osm-polygon-wikidata-only-trackio). It contains exactly three plots: a text-coverage funnel, the top ten Wikipedia languages plus `Other languages`, and dataset composition on a logarithmic scale. The run is a static snapshot with no pipeline timeline.

 - `Polygons with Wikipedia or Wikivoyage text`: polygons satisfying the Wikipedia condition or sharing a Wikidata entity with at least one non-empty Wikivoyage document. Each polygon is counted once.
 - `Text coverage`: `combined text-covered polygons / all dataset polygons` in the continent row.
