This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Red, semi-transparent circles encode each car’s position along the two axes, with a title and axis labels providing context. The visualization is built with d3.csv to load the data, d3.scaleLinear for the x and y scales, and d3.axisLeft and d3.axisBottom to render the axes, which include gridlines via tickSize. The SVG output is styled with CSS for circle opacity and text font sizes.
