This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Each red, semi-transparent circle represents a car, positioned along the x-axis by horsepower and the y-axis by weight. Built with D3 v5, the code uses `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, along with `csv` to load the data and SVG circles for rendering. The chart includes labeled axes and a title to clarify the dimensions shown.
