This example shows a horizontal bar chart ranking 20 countries by their 2010 population, with country names on the y-axis and population values on the logarithmic x-axis. The visualization is built using React with D3 v5 APIs including `scaleBand`, `scaleLinear`, and `csv` for data loading. The chart renders bars as SVG rectangles with hover tooltips showing formatted population values, and loads its data from a GitHub-hosted CSV file.
