This example visualizes automobile data from a CSV file, plotting each vehicle as a circle based on its origin, horsepower, and weight. The chart uses color to encode weight and circle size to represent miles per gallon, with tooltips showing vehicle names. Built with the Vega-Lite API and D3.js, it loads data asynchronously and renders an interactive scatter plot that fits the full window. The visualization configures axes and label styles, and integrates Vega tooltip for hover details.
