This bar chart displays the total population estimates for the top 10 countries by population, using data from the UN population estimates. The visualization uses D3.js with `scaleBand` and `scaleLinear` to map country names to bar positions and population values to bar heights, while `axisLeft` and the `axes` utility from `@curran/responsive-axes` render the axes. The chart highlights a light gray inner rectangle behind the bars to separate the plotting area, and it sorts the data in descending order using `descending` to show the most populous countries first.
