This bar chart displays population counts for eight countries, with horizontal bars ordered from most to least populated. The visualization encodes data from a local CSV file using D3 scales—a linear scale for population and a band scale for country names. Rendering as SVG, the code applies D3’s `axisLeft`, `axisBottom`, `scaleLinear`, and `scaleBand` APIs to construct the axes and bars. Styling is handled through CSS, which sets bar fill colors, tick labeling, and the chart title.
