This area chart visualizes CO₂ emissions from 1960 to 2020 using a simple dataset of six yearly observations. The chart displays the trend with a light blue filled region beneath a steel blue line, making the growth over time immediately apparent. It uses d3.csv to load the data, d3.area to generate the filled path, and d3.scaleLinear with d3.axisBottom and d3.axisLeft for the axes. Rendered as SVG, the chart includes clear axis labels and a title, with the data encoded on the y-axis as absolute emission values starting from zero.
