A line-area chart shows India's CO2 emissions per capita over time, with the area filled in maroon beneath a smooth curve. The chart uses D3 v5's `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the SVG path, while `axisBottom` and `axisLeft` render labeled axes with gridlines. Data is loaded via `csv` from a GitHub gist and parsed as date objects, with the y-axis labeled "CO2 emissions (per capita)" and the x-axis as "Year."
