This example displays the top ten countries by population from the United Nations population prospects dataset, drawn as circles mapped along a linear scale. The React visualization uses D3 version 7 functions such as `scaleBand`, `scaleLinear`, and `max` to compute scales, while SVG elements are generated through React components for axes and marks. Country names are listed on the y-axis, and the chart loads CSV data via D3's `csv` method, with hover tooltips formatted from the parsed numerical values.
