This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars from the UCI Machine Learning Repository's Auto MPG Data Set. The visualization uses D3 v5 to render SVG circles, with each point representing a single car. The code employs D3's `scaleLinear` for both axes, `axisLeft` and `axisBottom` for the coordinate system, and `extent` to compute the data domain. The raw CSV data is loaded and parsed via D3's `csv` method.
