A horizontal bar chart displays the 2020 population estimates for ten countries, ordered by country name. The chart uses teal bars against a light background, with a formatted population label on the x-axis. The visualization is built with React and D3 v7, using `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Data is loaded from a CSV of UN population figures, and SVG rendering with CSS styling creates the final polished appearance.
