This line chart visualizes carbon emissions from 1740, plotting year against total emissions as a smooth, rounded curve. The graph uses D3 v5’s `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate the SVG path, while `csv` loads external data. The chart includes labeled axes, a title, and gridlines, with a maroon stroke for the line and sans-serif text styling.
