This scatter plot visualizes the relationship between vehicle horsepower and weight using 392 cars from the auto-mpg dataset. D3’s `csv` loads and parses the data, while `scaleLinear` and `extent` map attributes to SVG coordinates. Circles with fixed radius represent each car, rendered with axes generated by `axisLeft` and `axisBottom`, including gridlines and custom labels. The visualization uses d3.v5 and an SVG rendering approach, with styles applied via CSS for opacity and typography.
