This scatter plot displays the relationship between horsepower and weight for a dataset of cars, with each circle representing a vehicle. The visualization uses D3 v6's `scaleLinear` for both axes, `axisBottom` and `axisLeft` for ticks, and SVG circles with a fixed radius. Data is loaded from a CSV file via `csv()` and parsed into numeric values. Axes include grid lines and rotated labels, while the title and axis labels are styled using custom CSS classes.
