A filled area chart displays India’s annual CO2 emissions per capita over time, with a maroon smoothed curve against a gray grid. Built with D3 v5, it uses `scaleTime` and `scaleLinear` for axes, `area` with `curveBasis` for the path, and `axisBottom`/`axisLeft` for ticks. Data loads from a remote CSV via `d3.csv`, mapping year strings to dates and emission values for rendering in SVG.
