leafdown: Interactive Multi-layer maps in Shiny apps

on YouTube ↗05m

" summary

Leafdown is an R package that embeds interactive multi-layer maps in Shiny dashboards, using the Meteostat monthly dataset of 2000 weather stations to link state, county and station data. Maps support drill down from state to county to station with selectable regions that update charts and tables, reducing clutter and improving performance. A few lines of code create linked visualizations of temperature and precipitation over time; the GitHub repo contains examples and working demos of the approach.
