Cars Scatter Plot
This scatter plot displays the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red semi-transparent circle represents a car, with the x-axis mapping horsepower and the y-axis mapping weight. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct axes, while `csv` loads the external data. All marks and text are rendered as SVG elements within a 960×500 viewport.
