This bar chart displays the top ten countries by 2020 population, using horizontal bars that scale linearly from zero. Built with React and D3, the SVG renders through a `d3.scaleBand` for the y-axis categories and a `d3.scaleLinear` for the x-axis values, with margins applied via a translation group. Data is loaded asynchronously from a CSV URL using `d3.csv`, and the chart updates after filtering to the first ten rows. The visualization demonstrates the standard margin convention by positioning all bars within a padded inner plotting area.
