This example displays a scatter plot from a car dataset, showing the relationship between horsepower and highway MPG, with each orange circle representing a car. It loads data from a CSV file via `d3.csv`, parses numeric values, and scales the data using `scaleLinear` with `extent` for the domains. SVG circles are bound to the data, and axes are rendered with `axisBottom` and `axisLeft`. D3 v6 handles all DOM manipulation and data joins, while axis labels are positioned via SVG text and `transform`.
