This bar chart displays the population of ten countries, with bars ordered alphabetically by country name. The chart uses D3 v5's `scaleLinear` and `scaleBand` to map population values to bar widths and countries to vertical positions, respectively. Data is loaded from a CSV file via D3's `csv` function, and the SVG bars are appended and sized through the `selectAll` and `attr` methods. The rendering occurs in an SVG element with a fixed width and height.
