This scatter plot visualizes the relationship between horsepower and miles per gallon (MPG) for a dataset of cars, with each red semi-transparent circle representing a single vehicle. The chart uses D3 v5’s `scaleLinear`, `axisLeft`, and `axisBottom` to construct axes with gridlines, while `csv` loads the auto-mpg data from a remote URL. The SVG rendering includes labeled axes and a title, with circle positions mapped via scaled x and y coordinates.
