This example visualizes the relationship between miles per gallon, horsepower, vehicle weight, and origin using a scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository. The visualization encodes weight as point size and color as origin, with tooltips revealing car names. It is built with the Vega-Lite API, running through Vega and Vega-Lite rendering pipelines, and dynamically sizes the chart to the browser window. Data is loaded asynchronously via d3.csv, while a custom configuration adjusts axis and label styling.
