This visualization presents the largest 5 countries by population, using horizontal bars segmented by religion to show the distribution within each country. Built with the Vega-Lite API, it loads data from a CSV file and renders the chart using SVG. The code configures axis styles, tooltips, and uses a custom `config.js` for appearance, with the final visualization fit to the window size. It leverages the vega-lite-api library, d3.csv for data loading, and vega-tooltip for interactivity.
