This visualization displays India’s annual CO2 emissions per capita over time as a filled area chart. The area path is generated with `d3.area` and `curveBasis`, while `d3.scaleTime` and `d3.scaleLinear` map years and emission values to pixel coordinates. Axes are drawn using `d3.axisBottom` and `d3.axisLeft` with gridlines, and the data is loaded via `d3.csv` from a GitHub gist. The SVG rendering uses a maroon fill for the area, with axis labels and a title styled via CSS.
