This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, with each point representing an individual vehicle. The SVG rendering uses d3.scaleLinear with extent-derived domains, d3.axisBottom and d3.axisLeft for axes, and d3.csv to load the auto-mpg dataset. The circles have a fixed radius with red fill and partial opacity, while axis labels and title are styled via CSS classes. Grid lines are drawn using tickSize to span the inner chart area.
