This scatter plot from the Auto MPG data set (UCI Machine Learning Repository) shows the relationship between horsepower and weight for 398 cars, with each red, semi-transparent circle representing a vehicle. Built with D3 v5, the visualization uses `scaleLinear` for both axes, `extent` to compute domains, and `axisBottom`/`axisLeft` for labeled ticks. The SVG rendering applies margins, rotated axis labels, a title, and removes domain lines to emphasize the data points.
