This scatter plot visualizes the relationship between vehicle weight and horsepower using data from the auto-mpg dataset loaded via `d3.csv`. The visualization employs `d3.scaleLinear` with `d3.extent` and `.nice()` to map weight on the x-axis and horsepower on the y-axis, with blue semi-transparent circles rendered as SVG elements. Axes are drawn using `d3.axisBottom` and `d3.axisLeft`, complete with rotated labels, tick marks, and a title. The chart uses margins to position a grouped `<g>` element, demonstrating fundamental D3 data binding and scales.
