This example visualizes the relationship between miles per gallon and horsepower for automobiles, with color encoding by origin and interactive tooltips displaying car names. It uses the vega-lite-api to construct a circle mark scatter plot, which is then rendered and configured via Vega-Lite, Vega, and d3.csv for data loading. The data originates from the UCI Machine Learning Repository’s Auto MPG dataset, and the view auto-sizes to the window with custom axis and label styling.
