This example displays a bar chart of population by country, sorted in descending order to highlight the most populous nations. The visualization is built programmatically using the Vega-Lite API, which constructs a specification that is then rendered by the Vega engine. The code registers Vega-Lite and Vega with the vega-lite-api library, uses D3’s CSV parser to load data from a Gist-hosted file, and applies custom configuration for axis styling and tooltips. Data originates from the UCI Auto MPG dataset, though the visualization itself plots country populations.
