This bar chart displays the population of ten countries for the year 2000, with country names on the y-axis and population values on the x-axis. The visualization is built with React, D3 v5, and SVG, using `scaleBand` and `scaleLinear` for positioning. Data is loaded from a remote CSV file, and axis tick labels are formatted using D3’s `format` function to abbreviate large numbers with "B" for billions.
