This example demonstrates a scatter plot of automobile data from the UCI Auto MPG dataset, where each point represents a car, with horsepower on both axes, color encoding region of origin, and size encoding vehicle weight. Hovering reveals the car name via tooltips. The visualization is built using the Vega-Lite API and rendered with D3.js, incorporating custom axis styling and a dark color scheme from the configuration file. Data is loaded asynchronously via D3’s CSV parser, and the chart is displayed across the full window with automatic resizing.
