This scatter plot displays the relationship between horsepower and weight for a dataset of cars, sourced from the auto-mpg.csv file. The visualization uses D3 v5’s `scaleLinear` to map data values to pixel coordinates, with axes generated via `axisBottom` and `axisLeft` and rendered as SVG elements. A dropdown menu allows selection among options A, B, and C, though its interaction is not shown. Red, semi-transparent circles encode individual car data points.
