A scatter plot displays the relationship between horsepower and weight for cars from the auto-mpg dataset. Each red circle represents an individual car, positioned along the x-axis by horsepower and the y-axis by weight, with both axes using linear scales. The visualization is rendered as an SVG using D3 v5, leveraging the `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct the plot. Data is loaded asynchronously from a CSV file via `csv`, and numeric fields are parsed before rendering.
