This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. It uses D3 v5 with SVG rendering, employing `scaleLinear`, `axisBottom`, and `axisLeft` to construct axes. Circles represent individual car models, with a red fill and partial opacity, conveying density. The code loads data via `csv` and builds the chart using margins, a title, and axis labels.
