This example presents a bar chart of worldwide religious populations, sorted in descending order and color-coded by religion, with tooltips showing exact values. It is built using the Vega-Lite API, which programmatically defines the bar mark and encodings, then renders through Vega with SVG output. The visualization loads CSV data via d3.csv and applies a custom configuration that removes axis domains, sets gray tick marks, and increases label and title font sizes for readability.
