A static line chart displays trends over time, plotting data points as circles connected by a path. The visualization uses React to render SVG elements, with D3 v5 utilities like `scaleLinear`, `extent`, and the `line` generator from `d3-shape` to map data coordinates. Axis components generate ticks and labels, while the `csv` loader fetches data from an external dataset. The chart includes axis labels and tooltips via SVG `<title>` elements, with styling applied through CSS classes.
