This horizontal bar chart displays the population of ten countries in the year 2000, with light green bars extending along a linear scale from left to right. The chart uses D3 v7 to load CSV data from a GitHub repository, with `d3.scaleLinear` mapping population values to the x-axis and `d3.scaleBand` positioning countries on the y-axis. Axes are generated using `d3.axisBottom` and `d3.axisLeft`, while tick labels on the x-axis are reformatted to abbreviate millions as "B" (e.g., 200M to 200B). The SVG rendering includes custom axis labels for "POPULATION-2000" and "Countries."
