This horizontal bar chart shows the population of ten countries in the year 2000, sorted by country name. The visualization uses React to render SVG elements, with D3.js v5 functions like `scaleBand`, `scaleLinear`, and `format` for positioning and tick labeling. Data is loaded from a remote CSV file using D3's `csv` function. The chart includes blue axis tick lines, green bars, and tooltips that display the population value when hovering over a bar.
