This scatter plot visualizes car dataset attributes, showing the relationship between horsepower and highway fuel efficiency (MPG) for different vehicle makes. Each circle represents a car, colored by its manufacturer using a Tableau10 ordinal color scale. The visualization is built with D3 v6, using `scaleLinear` for axes, `extent` to compute domains, and `axisLeft`/`axisBottom` for tick marks. Data is loaded asynchronously from a remote CSV file, with the legend manually constructed and positioned to identify each make.
