A horizontal bar chart displays the ten most populous countries in 2020, with a log-like linear scale mapping population values to bar widths and a categorical band scale mapping country names to vertical positions. The visualization is built with React components and D3 v7, using `d3.scaleBand`, `d3.scaleLinear`, and `d3.csv`. SVG rendering via React elements handles axes and marks, while data loads asynchronously from a GitHub-hosted CSV, and a loading message appears before the chart is drawn.
