This example displays a horizontal bar chart of the top 10 most populous countries, with population values from the United Nations World Population Prospects 2019 dataset loaded via `d3.csv`. The visualization uses React components for rendering SVG elements, with D3 scales and formatting applied through `scaleBand`, `scaleLinear`, and `format`. Bottom and left axes are constructed as separate React components, and each bar includes a native SVG `<title>` element for tooltips. The chart is styled with custom tick and mark colors.
