This example demonstrates an interactive scatter plot of automotive fuel economy data, showing the relationship between cylinder count and origin while revealing individual car names through tooltips. Rendered as a Vega-Lite visualization via the `vega-lite-api`, the chart applies a custom configuration for axis styling and font sizes before resizing to fit the viewport. The data is loaded asynchronously from a CSV using `d3.csv`. The plot uses semi-transparent, oversized marks with opacity encoding to avoid overplotting, and the code registers `vega-tooltip` for hover interactions.
