This example visualizes the world’s top five religions per country using a bubble chart, where circle size encodes population and axes map country and religion. Built with the Vega-Lite API, it loads CSV data via d3.csv, configures axes and tooltips through a custom config object, and renders as an SVG using Vega and Vega-Lite’s runtime. The visualization adapts to the viewport with autosize and includes an interactive tooltip handler from vega-tooltip.
