This example demonstrates a scatter plot of automobile engine displacement versus horsepower, with each point representing a vehicle and tooltips revealing the model name. Built with the Vega-Lite API, the visualization uses `vl.markPoint` and `vl.x().fieldQ()`/`vl.y().fieldQ()` for quantitative axes, while `vl.tooltip().fieldN()` handles categorical labels. Data is loaded asynchronously from an auto-mpg CSV via `d3.csv`, and the chart is rendered to SVG with vega-tooltip for interactive hover details. The code also customizes axis and font styles through a shared configuration object.
