This scatterplot shows the relationship between horsepower and weight for a collection of cars, with a title and labeled axes. The visualization encodes each car as a semi-transparent red circle using SVG, with scales derived from the data’s extent. The code uses D3 v7 APIs including `csv`, `scaleLinear`, `axisBottom`, and `axisLeft` to load data from a remote CSV, map values to pixel coordinates, and render grid lines and axis labels.
