This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, with each red circle representing a vehicle. The D3 v5 code uses `csv` to load the data, `scaleLinear` to map values to pixel coordinates, and SVG `circle` elements for rendering. Axes are generated with `axisBottom` and `axisLeft`, while `extent` determines the domain. The chart includes labeled axes and a title, with styling applied via CSS.
