This bar chart displays the top 10 countries by population in the year 2000, using a horizontal layout with light green bars. The visualization employs D3 v7 with SVG rendering, using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis. Data is loaded from a CSV file via `d3.csv`. Axes are drawn with `d3.axisBottom` and `d3.axisLeft`, with tick labels formatted using `d3.format` to abbreviate large numbers, while axis titles explicitly label the population values and country names.
