UV Index Visualizer fetches real-time and forecast UV data from currentuvindex.com for provided geolocation and renders six selectable visualizations:

• Solar Baker (animated pulsing sun disc sized by UV intensity)

• Beach Window (5-hour bar forecast with go/wait/skip verdict and burn-time readout)

• Burn Timer (time-to-sunburn for your Fitzpatrick skin type with heat-shimmer background)

• 5-Day Peaks (bubbling thermometer bars with best-beach-day indicator)

• Sun Arc charts Single-day (UV curves with sunrise/sunset markers and current-time line)

• Sun Arc charts Dual-day (UV curves with sunrise/sunset markers and current-time line)

All views are fully animated (8-frame loops), cache HTTP responses to respect device refresh cycles, and are configurable via schema fields for location, skin type, refresh interval, and UV target band.
