This scatter plot visualizes the relationship between vehicle weight and horsepower using data from the auto-mpg dataset. The D3.js (v5) code uses `scaleLinear`, `axisLeft`, and `axisBottom` to construct the axes, with gridlines drawn via negative tick sizes. It renders semi-transparent steel-blue circles via SVG, with categorical labels for the axes and title. The visualization applies the `extent` function for domain scaling and parses the CSV data to numeric values before rendering.
