A horizontal bar chart displays the population of ten countries in the year 2000, using green bars sorted alphabetically by country name. The visualization is built with React and D3 v5, employing `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. Data is loaded from a remote CSV file via `d3.csv`, with population values multiplied by 1000. SVG rendering includes custom `AxisBottom` and `AxisLeft` components, while tooltips show formatted values using D3's `format` function.
