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 using d3.scaleLinear for both axes. The chart includes labeled axes, tick marks, and a title, all rendered as SVG elements. The code uses d3.csv to load the data, d3.extent to set domains, and d3.axisBottom and d3.axisLeft to generate the axes.
