This visualization presents a scatter plot of auto-mpg data from the UCI Machine Learning Repository, using points to show vehicle weight versus horsepower. Color encodes the country of origin, while point size maps to miles per gallon. The plot is built with the Vega-Lite API, registering Vega and Vega-Lite libraries, and uses D3’s CSV parser to fetch data from a Gist. The code configures tooltips via vega-tooltip and customizes axis and label styling through a separate config object.
