This example displays a horizontal bar chart of population data for ten countries, comparing values like China, India, and the United States. The visualization uses D3.js v5 with SVG rendering. The code imports specific functions—`csv`, `scaleLinear`, `scaleBand`, and `max`—from the D3 library to parse the CSV file and map population counts to bar widths. Bars are positioned vertically using `scaleBand` on the country names and horizontally using `scaleLinear` for population values, with the data loaded asynchronously via `csv('data.csv')`.
