This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Using D3 v5 with SVG rendering, it maps each car to a red, semi-transparent circle whose position is determined by linear scales for both axes. The chart includes labeled axes with grid lines, a title, and formatted tick marks generated via `d3.axisBottom` and `d3.axisLeft`, with data loaded asynchronously via `d3.csv`.
