This bar chart displays the top ten most populous countries in the year 2000, sorted in descending order of population. The visualization uses D3.js v5 to load CSV data from a GitHub repository, scales both axes with `d3.scaleBand` and `d3.scaleLinear`, and renders the bars as SVG rectangles. Axis ticks and labels are generated using `d3.axisLeft` and `d3.axisBottom`, with population values formatted using `d3.format`.
