This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, displaying each vehicle as a semi-transparent black circle. The D3.js v6 code uses `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to construct the axes with grid lines and labels, while `csv` loads the remote dataset. The SVG rendering applies a light gray background and custom styling for ticks and titles.
