This visualization presents a horizontal bar chart comparing the populations of ten countries in the year 2000, sorted alphabetically by country name, with population values scaled to thousands. The chart uses D3.js scale functions to map the data to SVG rectangles, while React components structure the axes and marks. Data is loaded from a remote CSV file via D3's `csv` function, and tick labels are formatted using D3's `format` utility to abbreviate large numbers (e.g., “1.2B”).
