This bar chart displays the populations of the ten most populous countries, with countries on the y-axis and population counts on the x-axis. Built with D3.js v5, it uses `scaleLinear` and `scaleBand` to map data, and `axisBottom` and `axisLeft` for custom axes. Population values from a CSV file are formatted with abbreviations (e.g., 'B' for billions), and the chart removes default axis lines for a cleaner look. All elements render as SVG.
