This scatter plot from the UCI Machine Learning Repository’s Auto MPG dataset compares car horsepower on the x-axis against weight on the y-axis. Each circle represents a car, rendered using SVG with a fixed radius and semi-transparent red fill. The visualization uses d3.csv to load the data, d3.scaleLinear with d3.extent for scales, and d3.axisBottom and d3.axisLeft for axes. Axis labels and a title are added as SVG text elements.
