This bar chart displays the 2010 populations of 30 countries, ranked from largest to smallest, using a horizontal layout. The visualization loads data from a CSV file hosted on GitHub and renders it with React and SVG. The implementation uses D3 v5 for data processing and scales, specifically `csv`, `scaleBand` for the y-axis, and `scaleLinear` for the x-axis, with custom components for axes and marks. Blue tick lines and light green bars are rendered, with tooltips showing formatted population values.
