This visualization displays a scatter plot of automobile data, mapping miles per gallon against horsepower. Points are colored by country of origin and scaled in size by vehicle weight, with tooltips showing car model names. The example demonstrates the vega-lite-api library, which provides a JavaScript interface for building Vega-Lite specifications, combined with Vega and vega-lite for rendering. Data is loaded asynchronously via d3.csv from a remote CSV file containing auto-mpg statistics. The visualization uses SVG rendering, custom axis styling from a config object, and adjusts to fill the browser window.
