I built it as plain HTML + vanilla JavaScript + Chart.js, served statically; the browser talks to <code>api.worldbank.org</code> directly (permissive CORS), so no backend is required.</p> <h2 id="features">Features</h2> <ul> <li><strong>Search</strong> — 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.</li> <li><strong>Chart</strong> — 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.</li> <li><strong>Compare</strong> — scatter, bubble (size = third indicator), OLS regression with R², and Gapminder-style animated bubble chart.</li> <li><strong>Upload</strong> — drop in a CSV or Excel file; the app auto-detects columns, reshapes wide to long, and resolves ISO3 codes.</li> <li><strong>URL state</strong> — every control round-trips through query parameters, so any view is a permanent link.</li> <li><strong>Embed mode</strong> — append <code>?embed=1</code> to strip chrome and drop the app into an iframe.</li> <li><strong>Dark mode</strong> — respects <code>prefers-color-scheme</code>; toggleable.</li> <li><strong>Keyboard</strong> — <code>/</code> focuses the search box.</li> </ul> <p>An optional FastAPI proxy (server-side cache, UCDP-authenticated routes) ships alongside for developers who want it.</p>
