This example visualizes the relationship between engine displacement and horsepower for a sample of automobiles, with each point representing a car model and tooltips revealing its name. The visualization is built programmatically using the Vega-Lite API, which composes the chart specification through chained methods like `vl.markPoint`, `vl.x().fieldQ`, and `vl.y().fieldQ`. It loads CSV data via d3’s `csv` function, applies custom axis and label styling from a configuration object, and renders as an SVG using the Vega and Vega-Lite libraries with Vega-Tooltip for interactive hover details.
