COVID Analytics
Interactive pandemic data exploration across 50+ metrics and every country.
The Problem
Raw pandemic data is massive and opaque. The OWID dataset covers every country across 50-plus metrics, but making sense of a three-year pandemic requires more than a CSV download.
The Solution
An analytics dashboard with wave detection, seasonal pattern analysis, vaccination effectiveness modeling, and outlier detection — built directly on the OWID COVID dataset.
What it does
- Explore pandemic metrics across any country with interactive charts
- Detect pandemic waves with peak dates, intensity, and growth rates
- Uncover seasonal patterns and vaccination effectiveness trends
- Identify statistical outliers and data quality issues
- Switch between five analytics tabs without waiting with Suspense and React Query caching
What took work
- Processing half a million time-series rows for instant exploration
- Building wave-detection algorithms that work across different transmission patterns
- Keeping five analytics tabs snappy with React Suspense and React Query caching
