This example uses the Vega-Lite API to create a bubble chart showing the population of each religion across countries, with circular marks sized by population and colored by country. The visualization loads CSV data from a GitHub gist, renders with SVG via Vega, and includes tooltips for inspecting values. The code configures axes, labels, and styling for readability, while the chart automatically fits the window dimensions. It leverages D3 for data fetching, Vega for rendering, and Vega-Lite’s declarative encoding for marks and scales.
