This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository, plotting each car as a circle positioned by miles per gallon and horsepower, colored by country of origin, and sized by vehicle weight. Built with the Vega-Lite API, it registers Vega and Vega-Lite with a custom configuration that removes axis domains and enlarges label fonts for readability. Data is fetched asynchronously via d3’s `csv` loader, and tooltips are enabled through the vega-tooltip `Handler`. The visualization renders as an SVG, fitting to the browser window with padding, and includes interactive tooltips showing car names.
