This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red circle represents a car, with its position determined by the d3.scaleLinear scales for the x- and y-axes, and the chart includes labeled axes and a title. The code loads CSV data via d3.csv, converts numeric fields, and renders the SVG using d3.axisBottom and d3.axisLeft for the axes, with styling from external CSS.
