This responsive bar chart displays the top 10 most populous countries as of January 1, 2024, using data from the UN population estimates. It uses d3.scaleBand and d3.scaleLinear to map country names and population values to bar positions and heights. The visualization leverages the `observeResize` helper from `@drbagwell/responsive-viz-axes` for dynamic sizing, and renders axes through the `axes` function. The chart includes a gray inner rectangle behind the bars and uses `d3.select` and `join` for SVG element management.
