This is a novel visual built on real science: every U.S. DC fast‑charging site since 1999, played back month by month using the grammar of a weather map. The idea has an academic pedigree: geographers have shown for decades that new infrastructure spreads outward from established centers in wave‑like fronts, much like weather systems.

How the wind works. Dense, built‑out charging clusters behave like high‑pressure systems. Fast‑growing frontiers behave like low‑pressure systems moving away from them, and the wind blows down that gradient, out of the saturated cores toward where the next chargers are going in. Follow the wind and you are watching growth momentum.
In short: clouds = everything built · storm cells = recent openings · lightning = a large site going live · wind = where growth is headed. Press ▶ to run the timeline, switch views (Storm / Radar / Satellite), and click any station for its detail.
