This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset, loaded via `d3.csv` from a VizHub URL. It uses D3 v6’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes, with gridlines from tick sizes. The SVG circles are semi-transparent blue, showing density. Axis labels and a title are added, with margins applied around the main plotting area.
