A scatter plot of automotive data visualizes the relationship between the country of origin and horsepower, with each car represented by a semi-transparent circle. The visualization uses the Vega-Lite API with the `data(await getData())` method to load and bind the Auto MPG dataset from the UCI Machine Learning Repository, then applies a custom configuration to adjust axis styles and typography. The code registers Vega, Vega-Lite, and the Vega-Tooltip handler, and sets the chart dimensions to fill the browser window using `.width(window.innerWidth)` and `.height(window.innerHeight)` with an autosize fit option.
