This visualization displays the relationship between miles per gallon, horsepower, origin, weight, and car name from the Auto MPG dataset. The Vega-Lite API constructs a scatter plot where engine weight encodes point size and country of origin drives color, with a tooltip for each vehicle. It uses `vl.markCircle`, `vl.x().fieldQ('mpg')`, and `vl.y().fieldQ('horsepower')` for quantitative axes, while `config.js` customizes axis and label styling, and `getData.js` loads the CSV via `d3.csv`.
