This responsive bar chart visualizes the top 10 countries by total population using data from the UN population estimates. The visualization uses d3.scaleBand and d3.scaleLinear to map countries and population values to bar positions and heights, with d3.axisLeft for the y-axis. It leverages @curran/responsive-axes and @curran/un-population-estimates-2024 to handle resizing and data loading. A gray inner rectangle highlights the plotting area, and bars are rendered as SVG rect elements. The chart adapts its dimensions through the observeResize function.
