This scatter plot displays the relationship between model year and horsepower for a small set of cars, using steel-blue circles on a linear scale. Built as a reusable D3 chart function, it creates an SVG with axes labeled "Year" and "Horsepower", and the code employs `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to map data ranges. A dataset of five car entries, including years 2021–2023, is rendered with the chart function called on the document body, while a separate module offers a configurable version with setters for dimensions and margins.
