This visualization presents the Auto MPG dataset from the UCI Machine Learning Repository as an interactive scatter plot, mapping miles per gallon against horsepower. Each circle represents a car model, with color encoding the country of origin, size encoding weight, and tooltips revealing the model name. The code uses the Vega-Lite API (via the `vega-lite-api` wrapper) to define the chart declaratively, with D3.js handling CSV data loading. Custom configurations adjust axis styling and typography for readability, and the visualization auto-fits to the browser window dimensions.
