This example visualizes automobile data from the UCI Machine Learning Repository’s Auto MPG dataset, plotting origin on the x-axis, horsepower on the y-axis, and encoding mpg as circle size with tooltips showing car names. Built with the Vega-Lite API, it registers vega, vega-lite, and vega-tooltip in index.js, loads CSV data via d3.csv, and renders an interactive SVG chart configured with custom axis and label styling from config.js. The visualization updates dynamically to fit the browser window.
