This bar chart displays the population of ten countries in the year 2000, with horizontal bars representing each nation’s population size. The visualization uses React to render SVG elements, while D3 v5 handles data loading, scaling, and axis generation through `scaleBand`, `scaleLinear`, and custom `AxisBottom` and `AxisLeft` components. Population values are loaded from a CSV file via `d3.csv`, formatted with `d3.format`, and displayed with tooltips showing the precise figures.
