This visualization displays a bubble chart of religious populations by country, where each bubble’s size encodes the population value and its color distinguishes countries. The chart is built with Vega-Lite’s API (via `vega-lite-api`), using `markCircle` and encodings for x-axis country, y-axis religion, and quantitative size. Data is loaded asynchronously from a CSV using `d3.csv`, and the rendered SVG includes an interactive tooltip handler from `vega-tooltip`. The layout auto-fits the window dimensions.
