This scatter plot displays the relationship between horsepower and weight for a dataset of cars, with each circle representing a vehicle. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct axes with gridlines, while SVG circles are positioned using the scaled x and y values. Data is loaded asynchronously from a CSV file via `d3.csv`, and styling is applied through external CSS for tick text, axis labels, and the semi-transparent red circles.
