This bar chart displays the top ten countries by population for 2020, using horizontal bars sorted by country name. The visualization is built with React for component rendering and D3 v7 utilities for data loading and scales, including `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Data is fetched via D3’s `csv` parser from a GitHub gist, with SVG elements composed from reusable React components like `AxisBottom`, `AxisLeft`, and `Marks`.
