This visualization displays the population of ten countries in the year 2000 using a horizontal bar chart. The chart uses React with D3.js for data processing and scales, rendering SVG elements through the reusable AxisBottom, AxisLeft, and Marks components. Population values are parsed from a CSV file using D3’s `csv` function, formatted using `d3.format`, and displayed as green bars with tooltips, while the y-axis lists country names and the x-axis uses a custom tick format.
