This scatter plot visualizes the relationship between horsepower and weight for cars, with each red semi-transparent circle representing a vehicle. The visualization uses D3 v5’s `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to map the data and render gridlines, while data is loaded from a CSV of the auto-mpg dataset. The SVG rendering includes axis labels and a title, with the code converting all numeric fields from strings on import.
