This scatter plot visualizes 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 single car, with position determined by its horsepower and weight values on the respective axes. The visualization uses D3 v5’s `scaleLinear`, `axisLeft`, and `axisBottom` APIs to construct the chart, loading CSV data via the `csv` function and rendering to an SVG canvas.
