This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Red semi-transparent circles mark each car, with axes labeled and a title displayed. Built with D3.js v5, the code uses `d3.csv` for data loading, `d3.scaleLinear` for scaling, and `d3.axisLeft` and `d3.axisBottom` for axes. SVG rendering is used, with margins and tick formatting handled explicitly.
