A bar chart visualizes historical figures from the Pantheon dataset, comparing their Heritage Price Index (hpi) across ten countries while color-coding by occupation. The visualization filters the raw CSV data to include only mathematicians, statisticians, computer scientists, engineers, inventors, biologists, and physicists from the United States, United Kingdom, Germany, Italy, China, India, Japan, South Korea, Canada, and France. Built with the Vega-Lite API, the chart uses `vl.markBar()` and encodes fields for country, hpi, occupation, and tooltip with figure names. The code loads data via D3's `csv`, applies custom configuration for axis styling, and renders through Vega, Vega-Lite, and vega-tooltip libraries.
