This scatter plot displays the relationship between horsepower and weight for 398 cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each blue, semi-transparent circle represents a vehicle, with axes labeled “Horsepower” and “Weight” alongside a title. Built with D3 v5, the visualization uses `d3.csv` to load the data, `d3.scaleLinear` and `d3.extent` for scaling, and `d3.axisBottom` and `d3.axisLeft` to render gridlines and tick marks. The SVG rendering includes custom margins, axis labels, and a title, with styling applied via CSS.
