This bar chart visualizes the top 10 countries by total population using data from the UN Population Estimates 2024. The chart renders bars with a gray inner rectangle background, using D3's `scaleBand` and `scaleLinear`. The code filters the dataset for countries, sorts it in descending order, and slices the top 10 entries. It employs `axisLeft` and custom `xAxis`/`yAxis` functions, along with `xAxisLabel` and `yAxisLabel` utilities to label the axes.
