This visualization shows India’s annual CO2 emissions per capita over time as a smooth filled area chart. The area’s height encodes emission values across years, with axes labeled for clarity. Built with D3 v5, it uses `scaleTime` and `scaleLinear` for positioning, `area` with `curveBasis` for the smooth shape, and `axisBottom`/`axisLeft` for gridlines. The data loads from a CSV hosted on GitHub Gist, with the SVG rendering and styling handled via `select`, `csv`, and CSS classes.
