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 car, with its x-position scaled by horsepower and y-position by weight. Built with D3 v5, the visualization uses `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct axes and map data values to SVG coordinates. The code loads CSV data via `csv` and appends circles to an SVG element, with styling defined in an external stylesheet.
