This example displays the top 10 most populous countries as a horizontal bar chart, with country names on the left axis and population values along the bottom axis. It uses React components to render SVG elements, with D3 v5’s `scaleBand` and `scaleLinear` for positioning and scaling, and manually drawn axis components (`AxisBottom`, `AxisLeft`) to avoid D3 axis helpers. Data is loaded asynchronously via `useData` and D3’s `csv` from the United Nations World Population Prospects 2019 dataset, with the chart updating once the data arrives.
