NOAA Storm Events Explorer
A Shiny demo of task-centered filters, linked views, and restrained animation.
Live demo: the app opens in a new tab. A sleeping free-tier instance may take a few seconds to start.
Audience task
Compare exposure across place and time
Choose hazards and a measure, play through the months, then inspect the largest reported incidents behind the summary.
02 · Connect
Keep context visible
The state map, seasonal chart, hazard ranking, and incident table update from the same reactive data boundary.
03 · Animate
Use motion to encode time
The month slider’s play control moves through a real temporal sequence while the annual chart preserves context.
Data boundary
Read the evidence honestly
The demo uses the cleaned 2024 NOAA Storm Events teaching extract. Rows are event records, not necessarily unique physical storms. Reported damage estimates contain zeros and missing reports and are not a complete accounting of loss.
