An orange semi-transparent area chart displays the monthly U.S. unemployment rate from 1948 to 2021. The visualization loads CSV data via `d3.csv`, parses dates with `d3.timeParse`, and renders an SVG path using the `d3.area` generator. Time and linear scales (`d3.scaleTime`, `d3.scaleLinear`) position the axes, which are drawn with `d3.axisBottom` and `d3.axisLeft`. The chart includes labeled axes and a title, with all styling applied via CSS classes.
