This example shows two line charts comparing unemployment rate over time, with a pink line and a blue line plotted from hardcoded data arrays. The rendering relies on D3’s `line` generator to convert data points into SVG path strings, which are then drawn as `path` elements with `fill`, `stroke`, and `stroke-width` attributes. Axis labels for "Unemployment Rate" and "Year" are added as SVG text elements, rotated for the vertical axis. The code deliberately omits scales, using raw coordinates and fixed margins instead of an axis scale or ticks.
