This area chart shows Tesla stock price over time, with a red line tracing yearly price changes and a light pink fill underneath to emphasize the area between the line and the baseline. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `axisBottom`/`axisLeft` to map date and price data from a CSV, while the `line` and `area` generators with `curveBasis` create the smooth connected path and filled region. Data is parsed with `d3.timeParse` and rendered as SVG.
