This scatterplot visualizes the relationship between horsepower and weight for a dataset of cars, with each red circle representing a vehicle. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while `csv` loads the auto-mpg dataset from a remote URL. SVG circles are positioned via the scales, and gridlines are drawn using tick sizes that span the plot’s inner dimensions.
