This scatter plot from the UCI Machine Learning Repository Auto MPG dataset visualizes the relationship between car horsepower and weight. Each red, semi-transparent circle represents a car, with position determined by linear scales mapping horsepower to the x-axis and weight to the y-axis. The SVG rendering uses D3 v5 functions including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct the axes with descriptive labels. The visualization includes a title and uses D3's `csv` method to load and parse the data before rendering.
