A scatter plot visualizes 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 APIs including `csv`, `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to load data, map scales, and render axes. The SVG chart includes labeled axes, a title, and a grid of tick lines, rendered entirely client-side.
