The chart is rendered as SVG using React components for the axes and marks, while D3’s `scaleBand` and `scaleLinear` handle the positional scales. Data is loaded from a CSV file via a custom `useData` hook and the `d3.csv` function, with population values formatted using `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fb12e725bbf4b289c09488a065d1112?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
