This horizontal bar chart displays the populations of 20 countries in 2010, sorted by country name. The visualization uses D3 v5 scales and SVG rendering within a React framework to map population values to bar lengths. The code employs `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and `csv` to load remote data. Population values are formatted using `siFormatter` to abbreviate large numbers (e.g., converting billions to "B").
