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, with positions determined by d3.scaleLinear for both axes. The chart includes labeled axes, grid lines, and a title, all rendered as SVG elements. The code uses d3.csv to load the data, d3.axisLeft and d3.axisBottom for the axes, and d3.extent to set the scales’ domains.
