This area chart displays yearly runs scored, with a smooth curve and a sky-blue filled region beneath the line. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the SVG path, while axes are rendered with `axisBottom` and `axisLeft`. Data is loaded from a CSV file via `d3.csv`, with years parsed as dates and runs as numbers. The chart includes formatted tick labels and prominent axis titles, all styled with CSS.
