This bar chart displays the population values for the top ten countries in the year 2020, sorted by the source CSV data order. It uses D3 v7 with SVG rendering, employing `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisBottom`/`d3.axisLeft` to visualize the data. The chart reads from a GitHub-hosted CSV file and uses a module-based structure with separate components for axes and marks.
