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, positioned by its horsepower on the x-axis and weight on the y-axis. The code uses D3 v5’s `csv` loader to fetch the data and `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes with grid lines. The SVG rendering includes labeled axes and a title, with styling applied via external CSS.
