leafdown: Interactive Multi-layer maps in Shiny apps

on YouTube ↗05m

" summary

Uses the Meteostat Weather's Record Keeper monthly dataset (≈2,000 US stations) to show a Shiny map workflow built with leafdown that moves between state, county, and station layers and links selections to time series and precipitation charts. Implements selectable regions linked to charts and drill down/up so users avoid clutter, compare aggregate (state) vs local (county/station) patterns, and fetch only needed data; works with a few lines of R and is on GitHub.
