This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, loaded via `d3.csv`. The SVG rendering uses `d3.scaleLinear` for both axes, with `d3.axisBottom` and `d3.axisLeft` to create gridlines and tick marks. Circles are appended with semi-transparent cyan fill to show data density. Axis labels and a title are added as SVG text elements, demonstrating a clear, labeled comparison of vehicle performance metrics.
