This example displays a responsive bar chart visualizing the top 10 most populous countries using data from the UN population estimates for 2024. The chart shows each country's total population in thousands, with bars rendered via SVG rectangles. The code uses the D3 library for data handling, including `scaleBand` and `scaleLinear` for scales, and the `@curran/responsive-axes` library for axis generation. Resizing is managed through `observeResize` from `@curran/responsive-axes`, ensuring the chart adapts to its container dimensions.
