This scatter plot displays the relationship between horsepower and weight for various car models, with each circle representing one vehicle. The encoding uses a linear scale for both axes, with a circular mark radius of 10 pixels. The visualization is rendered as an SVG using D3 v6, utilizing `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` functions. Data is loaded from a CSV file via `csv()` from D3, with axis labels and tick formatting applied. The chart includes a title and uses a semi-transparent steelblue fill for the circles.
