This scatter plot visualizes the relationship between horsepower and weight for a collection of cars, sourced from the UCI Machine Learning Repository’s Auto MPG dataset. Each red, semi-transparent circle represents a single car, with its horizontal position determined by horsepower and vertical position by weight. The visualization is built with D3 v5, using `scaleLinear` to map data values to SVG coordinates, `axisBottom` and `axisLeft` for labeled axes, and CSV data parsed via D3’s `csv` loader.
