This bar chart displays the top 10 most populous countries on Earth as of January 1, 2024, using data from the UN population estimates. The visualization is built with D3.js, employing `scaleBand` for the categorical country axis and `scaleLinear` for the population values. The code imports helper modules for axes and labels, and renders bars with `rect` elements. The accompanying video encourages users to fork and modify the visualization with their own dataset.
