This visualization uses the Vega-Lite API with D3.js to render a scatter plot of global religious demographics, showing the population sizes of various religions by country. The chart applies circular marks with size encoding to represent population values, sorted by country on the x-axis, with tooltips revealing exact population figures. Data is loaded asynchronously from a UCI Machine Learning Repository CSV via `d3.csv`. The code customizes the visual style through a Vega-Lite configuration object, adjusting axis labels and title fonts, while the Vega tooltip handler provides interactive hover details.
