I developed a static web app to explore World Bank WDI indicators directly from the browser. Loads in under a second, no backend, no cold start. Search 100+ curated indicators (or the full ~20k taxonomy), chart line/area/bar with country presets (OECD, EU27, SSA, BRICS, G7, LDC, LMIC, G20), compare indicators (scatter, bubble, OLS with R², Gapminder-style animation), upload your own CSV/XLSX, and share every view through a URL.
