This visualization displays the U.S. unemployment rate from 1948 to 2021 as an area chart, using an orange semi-transparent fill over a time-series line. The chart intentionally allocates less vertical height to the plot area, which improves the perception of the data by preventing the spikes from appearing stretched and distorted. Built with D3 v7, the code uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks and labels, and `d3.area()` to generate the SVG path for the area. The data is fetched from a CSV and parsed with `d3.timeParse`.
