EasyViz — a static WDI explorer
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.
EasyViz is a lightweight alternative to Streamlit-based dashboards. I built
it as plain HTML + vanilla JavaScript + Chart.js, served statically; the
browser talks to api.worldbank.org directly (permissive CORS), so no backend
is required.
Features
- Search — 100+ curated WDI indicators with fuzzy search via Fuse.js; optional one-click extension to the full ~20k-code taxonomy, cached locally for a week.
- Chart — line, area, or bar, with country presets (OECD, EU27, SSA, BRICS, G7, LDC, LMIC, G20, Default-20, All), adjustable year range, log scale, summary statistics, CSV export, and shareable URLs.
- Compare — scatter, bubble (size = third indicator), OLS regression with R², and Gapminder-style animated bubble chart.
- Upload — drop in a CSV or Excel file; the app auto-detects columns, reshapes wide to long, and resolves ISO3 codes.
- URL state — every control round-trips through query parameters, so any view is a permanent link.
- Embed mode — append
?embed=1to strip chrome and drop the app into an iframe. - Dark mode — respects
prefers-color-scheme; toggleable. - Keyboard —
/focuses the search box.
An optional FastAPI proxy (server-side cache, UCDP-authenticated routes) ships alongside for developers who want it.
