This scatter plot visualizes the relationship between horsepower and weight for cars, using data from the UCI Machine Learning Repository’s Auto MPG dataset. 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, `scaleLinear` for both axes, and `axisBottom` and `axisLeft` to render the grid lines and labels. The SVG rendering includes custom axis labels and a title, styled via external CSS.
