Iron Viz 2020
summary
Contestants work from a capital‑city dataset about air pollution, claiming 95% of people across 33 sample capitals live above the WHO safe PM2.5 level—about 107 million people—and they model how GDP shifts could move cities between unhealthy and healthy categories. Builds use Tableau Prep, regex, data densification, normalization to 0–1 for six metrics, set actions and parameter actions, animations, polygons and layered maps; final dashboards combine an area‑bar population view, map with flowing connectors, and story points, and one entry wins the Iron Viz crown.
