This scatter plot displays 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, revealing a positive correlation between the two variables. The visualization uses D3 v5 with `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while `csv` loads the external data. A styled title and axis labels clarify the chart, with SVG rendering and CSS controlling circle opacity and text appearance.
