This area chart visualizes carbon emissions production across multiple countries over time, using stacked colored regions to compare annual values. The code loads data from a CSV file via `d3.csv` and renders SVG paths using the `d3.area` generator, with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. It includes custom axis labels, rotated tick text, and an interactive legend built with SVG rectangles. Colors are assigned sequentially using HSL values, and axes are generated with `d3.axisBottom` and `d3.axisLeft`.
