This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Red, semi-transparent circles mark each car, with axes labeled clearly. The visualization uses D3 v5’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to map data and render the SVG chart, while the data is loaded via `csv` and processed with numeric type conversions.
