This example uses the Vega-Lite API with D3 to render a scatter plot of automobile data from the UCI Machine Learning Repository, displaying miles per gallon against horsepower. Each point is colored by country of origin and sized by vehicle weight, with tooltips revealing car names. The visualization employs the `vl` API to construct the mark and encodings, configures axis styling for readability, and uses `vl.scale` for non-zero-based axes. It renders to SVG using Vega-Lite's default renderer, with data fetched asynchronously from a Gist-hosted CSV.
