This example shows a scatter plot of automobile displacement against horsepower, with each point representing a car model and tooltips revealing the vehicle name on hover. The visualization uses the Vega-Lite API to declaratively define the mark encoding and scales, while D3's `csv` function loads the auto-mpg dataset from a GitHub gist. The chart renders as a full-window SVG using Vega's renderer, with Vega-Tooltip handling interactive hover details. Custom axis and label styling from the `config` object improves readability against a clean background.
