The chart is rendered as SVG in React, with the population data fetched as CSV from a GitHub repository. Axis components generate tick marks and labels, while the Marks component draws green rectangles whose width encodes population, with a native SVG `<title>` tooltip showing the formatted value in billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de254d9d0a58410ab63380c7925a75f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
