This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository, plotting miles per gallon against horsepower as colored circles representing the car’s origin. It uses the Vega-Lite API to declare the scatter plot, with point size mapped to vehicle weight and tooltips showing car names. The visualization is rendered as SVG via Vega, with D3.js loading the CSV data and Vega Tooltip providing interactive labels. Custom axis and label styling in the configuration improve readability, and the chart resizes to fit the browser window.
