This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository as a scatter plot, mapping miles per gallon, horsepower, origin, weight, and car name to the x-axis, y-axis, color, size, and tooltip channels. It uses the Vega-Lite API to construct the specification programmatically, with Vega and Vega-Lite for rendering and Vega-Tooltip for interactive hover details. Data is loaded via d3.csv, and the chart fills the browser window with a custom configuration for font sizes and axis styling.
