ETL PIPELINE
Data Source: World Bank Climate Change API (Simulated) - CO₂ emissions, renewable energy, temperature anomalies
ETL Process: Data extracted 2025-10-09, cleaned & normalized, network metrics pre-computed (degree, betweenness, clustering), layout positions stabilized, statistical aggregations embedded
Web Learning: Observable: Introduction to Data
Techniques Applied: Pre-computation of network metrics, embedded multi-year data snapshots for instant switching, efficient JSON storage format, data transformation pipelines (cleaning, normalization, enrichment), statistical summary calculations (mean, median, std dev), histogram visualization of degree distribution, data export functionality, zero API calls for sub-500ms load time
