This scatter plot displays the relationship between horsepower and weight for various car models, sourced from the auto-mpg dataset. The visualization loads data via `d3.csv` and encodes each car as a circle, using `d3.scaleLinear` for both axes. The code constructs the chart with `d3.select`, `d3.axisBottom`, and `d3.axisLeft`, and removes the default axes domains for a cleaner look. All marks are rendered as SVG elements, with styling applied through a linked stylesheet.
