This example visualizes the relationship between miles per gallon and horsepower for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Color encodes the car’s origin, and point size reflects vehicle weight, with tooltips revealing the model name. Built with the vega-lite-api, it registers the vega and vega-lite libraries, loads CSV data via d3.csv, and renders a fully window-fitted, interactive scatter plot with a custom dark-theme configuration.
