This scatter plot displays the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Using D3 v5, the code loads the CSV data, applies linear scales via `d3.scaleLinear`, and renders red, semi-transparent circles as SVG elements. Axes are generated with `d3.axisLeft` and `d3.axisBottom`, complete with tick marks, labels, and a title, all styled through CSS.
