This bar chart displays the population of ten countries using horizontal bars ordered by country name. The chart customizes its axes by formatting population values with abbreviations like “M” and “B” via `d3.format`, removing unnecessary axis lines, and adding grid lines through `axisBottom` with negative tick sizes. Built with D3 v7, it loads CSV data, scales values with `scaleLinear` and `scaleBand`, and renders the visualization as SVG.
