This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for both axes and `extent` to set the domain. Circles represent individual data points, colored red with partial opacity, while grid lines are generated via `axisBottom` and `axisLeft` with custom tick sizing. Axis labels and a title are appended as SVG text elements, and the data is loaded asynchronously using `csv` and parsed with numeric coercion.
