This example displays the top 10 most populous countries from the United Nations World Population Prospects 2019 dataset in a horizontal bar chart. The bars are rendered as SVG rectangles using React components, with axes generated via custom `AxisBottom` and `AxisLeft` components that leverage d3.scaleBand and d3.scaleLinear. Data loading is handled through d3.csv in a custom `useData` hook, which parses population values and slices the result to the first ten entries. The chart includes tick marks and labels for both axes.
