This visualization uses the Vega-Lite API to render a scatter plot of automotive data from the UCI Auto MPG dataset, loaded via d3.csv. The active chart displays vehicle origin on the x-axis and horsepower on the y-axis, with large translucent circular marks and tooltips showing car names. The code registers Vega-Lite with vega, vega-lite-api, and vega-tooltip, and applies custom axis and label styling from a config object. The visualization is responsive, fitting the full browser window.
