This area chart visualizes global CO₂ emissions over time. The graphic fills the space beneath the line with green, making the upward trend in emissions immediately visible against the chart's white background. The visualization is built with D3 v7, using the `d3.area` API to generate the shape and `d3.scaleLinear` for axis scaling. Data is loaded from a remote CSV file via `d3.csv`, and the final SVG is rendered with standard D3 axes, labels for "Year" and "CO₂ Emissions," and a clean sans-serif font.
