This scatter plot displays the relationship between vehicle weight and horsepower for a dataset of cars. Each semi-transparent steel-blue circle represents a single car model, with the chart titled "Horsepower vs Weight." The visualization uses D3 v5 APIs including `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to compute scales and render SVG axes. Data is loaded via `csv()` from the auto-mpg dataset, with numeric fields parsed before rendering. Grid lines are created through axis tick sizing, and axis labels are added as SVG text elements.
