This bar chart displays the populations of the ten most populous countries in 2020, using a horizontal layout with a log scale for the x-axis. The visualization is rendered as SVG elements, with axes and marks created through reusable React components. It leverages d3.scaleBand and d3.scaleLinear to map data, d3.csv to load the UN population dataset, and d3.format for tick labels. The styling uses custom CSS classes with the Poppins font and a teal color scheme for the bars.
