This chart displays the 2020 populations of ten countries using horizontal bars, with country names on the y-axis and an x-axis for population values from the UN Population 2019 dataset. The D3 v5 scales `scaleBand` and `scaleLinear` compute the layout, while React components for axes and marks map the data to SVG `<rect>` elements. Population values are parsed from the CSV into numbers via `useData`, and the bars are rendered within an SVG canvas.
