This 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, with position determined by the linear scales built using `d3.scaleLinear`, `d3.extent`, and `d3.axisLeft`/`d3.axisBottom` for axes. The SVG rendering includes labeled axes and a title, styled via CSS. Data is loaded as CSV with `d3.csv` and parsed to numeric values before being rendered.
