This example visualizes COVID-19 recovery counts across countries, using colored and sized circles to represent the recovered cases per nation. Data is loaded from an Auto MPG dataset, though the visualization maps it to Country and Recovered fields. Built with D3.js and the Vega-Lite API, it registers Vega and Vega-Lite libraries, configures tooltips via vega-tooltip, and renders a scatter plot with a dark customization theme, scaling circles by recovery values.
