This example renders a bar chart of the ten most populous countries using React and D3 v5, with data from the 2019 United Nations World Population Prospects. The chart is intentionally minimal, lacking axes and using only bars labeled with country names and value ticks generated by `xScale.ticks()`. SVG elements are created via React's JSX, with scales defined by `scaleBand` and `scaleLinear`. Data loads asynchronously through `d3.csv`, and the bars update once the top ten rows are fetched and parsed.
