This bar chart displays the populations of 30 countries for the year 2020, ranked by their total population values. The visualization uses React with D3 v5 scales and SVG rendering to map country names along the y-axis and population totals along the x-axis. Data is loaded from a CSV file hosted on GitHub, with population values converted to thousands. The chart includes axes with tick formatting that abbreviates large numbers (e.g., converting billions to "B") and features light green bars with blue tick marks, plus a hover tooltip via SVG `<title>` elements.
