This scatterplot visualizes U.S. auto industry trends, plotting engine horsepower against miles per gallon, with each car’s origin shown by color and its weight by bubble size. The interactive tooltip reveals the vehicle’s name on hover. The visualization is built using the Vega-Lite API, which compiles specifications to Vega for rendering via SVG, and the data is loaded from a CSV of the Auto MPG dataset using `d3.csv`. Custom axis and label styling come from a shared config object.
