A horizontal bar chart displays the populations of ten countries in the year 2000, ranked with country names on the y-axis and population count on the x-axis. The visualization uses D3 v5 scales, including `scaleBand` and `scaleLinear`, within a React framework to render SVG rectangles. Each bar includes a native SVG tooltip showing the population value in billions via `format('.2s')`. Data is loaded asynchronously from a remote CSV file using D3's `csv` function. Grid lines and axis labels use the Poppins font, with light green bars on a white background.
