This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository's Auto MPG data set. Each red semi-transparent circle represents a car, with positions determined by d3.scaleLinear scales for both axes. The visualization uses D3 v5 to load CSV data, parse numeric fields, and render SVG elements, including axes generated with d3.axisLeft and d3.axisBottom. The chart is styled with custom CSS, and the visualization runs within an SVG container as specified in the HTML structure.
