This visualization displays unemployment rates for California, Texas, and New York over time, using a multi-line chart where each state is a separate line. The data comes from the `@oabouhas/unemployment` dataset. The code uses d3’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to render axes and paths, with `d3.groups` to separate lines by state. The chart includes a light gray background, axis labels, and semi-transparent lines for readability.
