This gallery example shows the ten most populous countries as horizontal bars without axes or labels, highlighting only relative population sizes. It loads United Nations population data from a CSV file, sorts by 2020 estimates, and maps each country’s value to a rectangle’s width using D3’s `scaleLinear` and `scaleBand` for positioning. The React component manages state with `useState` and `useEffect`, while rendering SVG rects directly via JSX. D3’s `csv` function parses the remote data, which is then displayed through ReactDOM.
