This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Each red, semi-transparent circle represents a car, with position determined by linear scales mapping these attributes. The visualization includes labeled axes, grid lines, and a title. The code uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, rendering all elements as SVG within a fixed-width container.
